Capture changes from Amazon DocumentDB via AWS Lambda and publish them to Amazon MSK

When using a document data store as your service’s source of truth, you may need to share the changes of this source with other downstream systems. The data events that are happening within this data store can be converted to business events, which can then be sourced into multiple microservices that implement different business functionalities. Capturing the changes from data sources is called change data capture (CDC); you can implement it in different ways by different data technologies. In the case of Amazon DocumentDB (with MongoDB compatibility), you can implement CDC via change streams functionality. This feature simplifies the process to listen to committed changes to documents in a set of collections in real time. The events are also time-ordered within a stream, which makes the stream a reliable mechanism for state replication scenarios. In this post, I show how you can capture changes from Amazon DocumentDB by using AWS Lambda implemented in NodeJS. After the Lambda function captures the change events, it publishes them to Amazon Managed Streaming for Apache Kafka (Amazon MSK). Architecture By completing the steps in this post, you can create a system that uses the architecture illustrated in the following image. The flow of events starts when we make changes within a collection residing in the Amazon DocumentDB database. As the changes arrive, Amazon DocumentDB copies them into a change stream dedicated to that collection. A Lambda function connects to this change stream and polls these events. After the function filters out events other than insert, update, and delete, it publishes them to a Kafka topic in an MSK cluster. A Lambda function is a stateless component, and it has a limited lifespan. Because the polling activity should be continuous, we need to run the Lambda function on a schedule. This architecture uses Amazon EventBridge to schedule the function to run every minute. In this sample architecture, each Lambda function triggered by the EventBridge engine connects to Amazon DocumentDB and watches for changes for a predefined time period (15 seconds in this case). At the end of each poll cycle, the function writes the last polled resume token to another collection in the same Amazon DocumentDB database. This checkpoint mechanism allows Lambda functions to resume the polling activity without needing to replay all the events from the beginning of the stream. This checkpointing mechanism should be in place even if we choose to use a long-running application using a virtual machine or container-based compute infrastructure. This is because if the underlying compute instance is restarted or scaled out, the new instance needs to have a starting point rather than process the whole history. A change stream can hold up to 7 days of information (determined by the change_stream_log_retention_duration parameter), which can translate to a significant number of change events for active applications. For this post, we use Amazon DocumentDB version 4.0. Deploy the stack To deploy the sample architecture into your AWS environment, we use an AWS Serverless Application Model (AWS SAM) template. The template creates the following resources in your account: An Amazon DocumentDB cluster (version 4.0) An MSK cluster A Lambda function (function-documentdb-stream-processor) that polls the change streams event from the Amazon DocumentDB cluster and publishes them to the MSK cluster An AWS Cloud9 environment, which allows you to configure source and destination systems and run your tests A VPC and subnets A NAT gateway and internet gateway Other supporting resources such as security groups and AWS Identity and Access Management (IAM) roles You will incur some costs after creating this environment. To start your deployment, clone the GitHub repository to your local machine and install and configure AWS SAM with a test IAM user. AWS SAM requires you to specify an Amazon Simple Storage Service (Amazon S3) bucket to hold the deployment artifacts. If you haven’t already created a bucket for this purpose, create one now. The bucket should be reachable by the IAM user you use for deploying AWS SAM packages. At the command line, navigate to the cloned GitHub repository’s folder and enter the following command to package the application: sam package --template template.yaml --output-template-file output_template.yaml --s3-bucket BUCKET_NAME_HERE Replace BUCKET_NAME_HERE with the name of the S3 bucket that holds the deployment artifacts. AWS SAM packages the application and copies it into the S3 bucket. When the AWS SAM package command finishes running, enter the following command to deploy the package: sam deploy --template-file output_template.yaml --stack-name Blogstack --capabilities CAPABILITY_IAM --parameter-overrides docDBUser=masterUsername docDBPass=masterPass docDBClusterName=docDBCluster mskClusterName=blog-msk-clstr In the preceding command, you can supply your own stack name by changing the stack-name parameter’s value. This template also allows you to provide the following input parameters and override their default values: docDBUser docDBPass docDBClusterName mskClusterName When you run this command, AWS SAM shows the progress of the deployment. The deployment takes around 15 minutes and creates a main stack and a dependent stack for the AWS Cloud9 environment in AWS CloudFormation. You can also track the overall deployment status on the AWS CloudFormation console. When the deployment is complete, AWS SAM outputs the following parameters, which you need while doing additional system configurations. These parameters are also available on the AWS CloudFormation console, on the Outputs tab of the deployed stack named Blogstack. Connecting to your AWS Cloud9 environment An AWS Cloud9 environment is created for you automatically when you deploy the AWS SAM package. You need to further provision this environment with MongoDB and Kafka command line tools. To start provisioning your AWS Cloud9 environment, follow the URL that was provided by the Cloud9URL output parameter of the deployed CloudFormation stack. When the environment starts, go to the terminal section. Configure Amazon DocumentDB You can now install mongo shell onto your AWS Cloud9 environment. Use the following commands in the terminal: echo -e "[mongodb-org-4.0] nname=MongoDB Repositorynbaseurl= https://repo.mongodb.org/yum/amazon/2013.03/mongodb-org/4.0/x86_64/ ngpgcheck=1 nenabled=1 ngpgkey= https://www.mongodb.org/static/pgp/server-4.0.asc" | sudo tee /etc/yum.repos.d/mongodb-org-4.0.repo sudo yum install -y mongodb-org-shell You also need Amazon DocumentDB CA certificates to connect to your cluster. Use the following command to download the certificate to the current folder (~/environment): wget https://s3.amazonaws.com/rds-downloads/rds-combined-ca-bundle.pem Enter the following command connect to your cluster: mongo --ssl --host DOCUMENTDB_CLUSTER_ENDPOINT_HERE:27017 --sslCAFile rds-combined-ca-bundle.pem --username DOCUMENTDB_USERNAME_HERE --password DOCUMENTDB_PASSWORD_HERE In the preceding command, provide the cluster endpoint of the Amazon DocumentDB cluster that was output from the AWS SAM installation. Also provide your username and password that you used during the sam deploy command. Create a database (blogdb): We create two collections in the database. The first collection is named blogcollection; we use it as the data source for the change stream integration. Use the following command to create the empty blogcollection: db.createCollection("blogcollection") Enable change stream on this collection by running the following adminCommand command: db.adminCommand({modifyChangeStreams: 1, database: "blogdb", collection: "blogcollection", enable: true}); You need to also enable change streams in the cluster’s parameter group before it can be used. You can enable Amazon DocumentDB change streams for all collections within a given database, or only for selected collections. We use the second collection, checkpoints, to store the checkpoint document that holds the last processed resume token: db.checkpoints.insert({_id: 1, checkpoint: 0}) You can now issue the exit command to exit the mongo shell and continue with the next step: exit Configure the MSK cluster To configure the MSK cluster, you need to install Kafka into your AWS Cloud9 environment. Use the following commands in your AWS Cloud9 terminal to download Kafka from the source, extract it, and navigate to the bin folder: wget https://apache.mirror.colo-serv.net/kafka/2.7.0/kafka_2.13-2.7.0.tgz tar -xzf kafka_2.13-2.7.0.tgz cd kafka_2.13-2.7.0/bin Kafka binaries we use in this post require Java 8 or later versions. Check your environment’s Java version with the following command: java -version If you see a version below 1.8, issue the below commands to upgrade it to Java 8. sudo yum -y install java-1.8.0-openjdk-devel sudo alternatives --config java Select the 1.8 versions from the list. Find the bootstrap servers of your MSK cluster: To find the bootstrap server hostnames for your MSK cluster, navigate to the Amazon MSK console and choose your cluster. In the Cluster summary pane on the Details tab, choose View client information and copy the bootstrap servers host/port pairs. Within Kafka installation’s bin directory, issue the following command to create a topic to hold the events published by function-documentdb-stream-processor: sudo ./kafka-topics.sh --create --topic blog-events --replication-factor 1 --partitions 1 --bootstrap-server MSK_BOOTSTRAP_SERVERS_HERE Replace MSK_BOOTSTRAP_SERVERS_HERE with the value of the host/port pairs from the previous step. Test the solution To test the setup from end to end, you need to open a second terminal in your AWS Cloud9 environment. On the Window menu, choose New Terminal. In the first terminal, make sure you’re in the bin folder of the Kafka installation and issue the following command to start listening to the records in the Kafka topic: sudo ./kafka-console-consumer.sh --topic blog-events --from-beginning --bootstrap-server MSK_BOOTSTRAP_SERVERS_HERE As before, provide the value of the bootstrap server host/port pairs. In the second terminal, use mongo shell to connect to the Amazon DocumentDB cluster the same way you did earlier. Issue the following command to insert a document into blogdb.blogcollection: use blogdb; db.blogcollection.insert({"title" : "Blog Title 1"}) Add another document with the following command: db.blogcollection.insert({"title" : "Blog Title 2"}) In the first terminal, observe the changes on the Kafka topic as you add different documents to the collection. Cleanup To clean up the resources you used in your account, delete the stack from the AWS CloudFormation console. You can also delete the bucket you used for packaging and deploying the AWS SAM application. Conclusion This architecture shows how to capture state changes from Amazon DocumentDB via its change streams functionality and send them to Amazon MSK. You can adapt similar architectures to apply to other use cases, such as query segregation, event sourcing, data duplication, and more.

TOP JAVASCRIPT FRAMEWORKS FOR DEVELOPING ROBUST AND SCALABLE MOBILITY AND WEB SOLUTIONS

JavaScript popularity among the web developers has grown over the years. Why are JavaScript frameworks quite popular among developers?

Well, it’s because of the interactive and convincing features offered by them. The world of tech is always evolving, and each New Year comes with all sorts of innovations, so we need smart tools for fast-paced development and building feature-rich interactive web apps, javascript just fit into these requirements. Every now and then new frameworks come out with new unique capabilities. What’s the right JavaScript library/framework for us to use?

When it comes to choosing the right JavaScript Framework it is certainly confusing. Should consider pros and cons, web development project we deal with etc.

Keeping all aspects in mind, we highlight 5 JavaScript frameworks which are worth knowing. 1. AngularJS

• AngularJS is a JavaScript-based open-source front-end web application framework. It is built by Google, the framework is known for its speedy and agile work.

• Angular.js-Has great MVC which strings MVC components together automatically and saves you time. HTML is used as a declarative language that makes them more intuitive.

• AngularJS 2.0 – They are Faster and stress more on browsers like IE10/11, Chrome, Firefox, Opera & Safari, Chrome on Android, Windows Phone 8+, iOS6 & Firefox mobile. Give better performance and easy applicability. But AngularJS2.0 cannot work with the new web components like custom elements, HTML imports, shadow DOM etc.

• AngularJS 4.0-Roughly six month after the release of Angular 2, angular 4 is now available. Angular4 consume less space and run quicker than previous versions. Have decrease in the size of the generated code to approximately 60 %. They have used animations in their own package, so in case you don’t use animation excess code won’t end up in your creation package.

• AngularJS 5.0– New version of angular was released in Nov 2017. It simplifies progressive web application, also provides a feature to get the native mobile applications with the mobile web apps. Have build optimizer tool which removes unnecessary runtime code as well as additional parts. Also comes with typescript 2.3 that makes the rebuilt super-fast.

2. React.js React is a JavaScript library for building user interfaces that combine the speed of JavaScript and uses a new way of rendering web pages, making them highly dynamic and responsive to user input. Developed by a collaboration of Facebook and Instagram and it was released in March 2013.

Advantages • Easy to learn-With lots of documentation, tutorials and training sessions makes anyone who comes from the JavaScript background can easily learn and use them. • Extremely efficient: Since it creates its own virtual DOM that gives you enormous flexibility and amazing gain in performance. • SEO friendly- React.js can run on the server side and the virtual DOM act as a regular web page in Browser. • Best Developer tools- React has design and debugging tools available for Chrome and Firefox. Individual components can be selected, examined and could alter their current properties and state if needed. 3. Vue.js Vue.js an open-source progressive JavaScript framework with various optional tools for building user interfaces. Developed in Dec 2017, Vue.Js framework focuses more on the front end. This framework is capable of boosting single-page applications when used in combination with modern tools and other supporting libraries.

Advantages • Small in size- Framework is 18–21KB and takes no time for the user to download and use it. Faster than all other frameworks

• Simple-Easy to understand because of its simple structure. Any template can be developed without time lag. Also, a user can easily trace the block with errors.

• Easy to integrate- As a JavaScript framework, it could be easily integrated with existing applications built on JavaScript.

• Detailed documentation-With detailed documentation, a user can easily develop his own web page or application.

4. Ember.js Ember.js is an open-source JavaScript web framework, based on the Model–view–view model (MVVM) pattern. It helps to create a single page web application, desktop, and mobile apps. E.g.:-Apple Music app

Advantages • Ember Data library-Ember data library includes features needed for communicating with a restful API. Don’t have to write your own program, we just have to define parameters and rest will be covered by ember.

• Ember CLI-Provides all generators and tools to handle third-party add-ons and to combine and rearrange JavaScript.

• A built-in testing tools-Ember-cli application is supplied with QUnit which act as a default testing framework. But others are supported through third-party add-ons.

• Active community and support.

5. Meteor.js Meteor, or MeteorJS, is a free and open-source isomorphic JavaScript web framework written using Node.js. Meteor.js is built around many small packages, like MongoDB or jQuery.

Advantages

Single Language Frontend, backend, and database are to be written in one single language-JavaScript. This Feature also works for the client as well as server side.

Real-time web development-Get updated automatically when underlying changes data changes.

Fast-Has a large community to get on with the basics really fast.

Easy to learn-JavaScript is free from CSS, HTML which makes the development process really simple. Has large community support, and with single language can learn it with ease.

To choose out the best framework can be a demanding task. For the particular purpose they were created for, they seem to be doing the best job at it. However, it’s not about the number of features that the particular framework can provide, but finding the right tool for the problem at hand. We at ti Technologies figure out the right JavaScript frameworks as per your project needs, general framework functionality, client’s long terms goals and the solutions that can save time and money.

Installing MongoDB

MongoDB runs on every operating system. Mac OS, Linux, Windows. First, you need to download MongoDB. Go to http://mongodb.com and click the top rightmost button: "Get MongoDB". Click on the "Server" tab and choose your operating system as you wish. I'm a windows user so I choose Windows 64-bit x64 and MSI package. If you downloaded the package, run and install the database. You may install mongo as a service so you don't need to start it every time. Don't worry if you didn't install it as a service, I'll show you how to run it. After you install you may want to add "mongo" to your environment variables. Click windows start menu type "Environment" and click the result. You should see the window shown in the image

Add the path of your MongoDB installation to PATH variable. This is the path to my default installation folder: "C:\Program Files\MongoDB\Server\4.0\bin". So go ahead and add this path to your user variables.

If you able to follow the instructions, you should be good to go. Now open command prompt once again. and type mongo . That’s it. You are connected to MongoDB. 

Stop MongoDB

MongoDB installed as a service to your Windows machine and it’ll start when you open your PC. Let’s stop the service and see how to manually start MongoDB. First of all, stop the MongoDB by typing “net stop MongoDB” in your command prompt. 

Start MongoDB

“mongo” command basically opens a client for you in your command prompt. If you want to start you MongoDB Server you should write “mongod”. After starting your MongoDB instance open another command prompt but don’t close the first one and type “mongo” this time (no “d” at the end). If you want to start your MongoDB with a different data folder you can run this command

mongod --dbpath “C:\data\db”

Hint: If you want to stop your MongoDB instance just press Ctrl+C in your command prompt which we typed “mongod” command.

Hint: If you are getting an error about permission, basically start your command prompt int Admin privileges.

Hint: If you want to start your MongoDB rather than default port which is 27017, you can use this comman: mongod --port 27018 . You can also connect to MongoDB with different port using this command: mongo --port 27018

See you in the next article. We will write some code on MongoDB.

Monitoring metrics and setting up alarms on your Amazon DocumentDB (with MongoDB compatibility) clusters

Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads. You can use the same MongoDB 4.0 application code, drivers, and tools to run, manage, and scale workloads on Amazon DocumentDB without having to worry about managing the underlying infrastructure. As a document database, Amazon DocumentDB makes it easy to store, query, and index JSON data. Amazon DocumentDB gives you the ability to monitor over 50 Amazon CloudWatch metrics, including CPU utilization, BufferCacheHitRatio, read and write IOPS, MongoDB opcounters, and more. For a detailed list of the CloudWatch metrics, see Amazon DocumentDB Metrics. You can monitor these metrics at the cluster, instance, or role level (for more information about roles, see Managing Amazon DocumentDB Users). In addition, other services can use the metrics, such as Amazon Simple Notification Service (Amazon SNS) to set notification alarms when a metric breaches a predefined threshold. This post walks through how to use CloudWatch metrics to monitor your Amazon DocumentDB cluster on the AWS Management Console. We also create an alarm and set up a notification through Amazon SNS to send an email when a metric breaches a predetermined threshold. Prerequisites To use the CloudWatch metrics, you must first provision an Amazon DocumentDB cluster. For instructions, see Getting Started with Amazon DocumentDB. Monitoring a cluster’s status with Amazon DocumentDB To view the status of your clusters, do the following: On the Amazon DocumentDB console, in the navigation pane, choose Clusters. In the Cluster identifier column, find the name of the cluster that you’re interested in. To find the status of the cluster, read across that row to the Status column, as shown in the following screenshot. In addition to being active, the cluster status can be in a number of different states, including deleting, failing-over, and upgrading. For a complete list of status values and their descriptions, see Cluster Status Values. Next, we look at how to check the status for individual instances within the cluster. Monitoring an instance’s status with Amazon DocumentDB To view the status of the individual instances in your cluster, do the following: On the Amazon DocumentDB console, in the navigation pane, choose Instances. In the Instance identifier column, find the name of the instance that you’re interested in. To find the status of the instance, read across that row to the Status collumn. In addition to being available, the instance status can be in a number of different states, including backing-up, creating, and deleting. For a complete list of status values and their descriptions, see Instance Status Values. You can view metrics at the cluster or instance level, and the instance must be in the available state before metrics can be viewed. You can view metrics two different ways on the console: via the Amazon DocumentDB console or the CloudWatch console. CloudWatch allows you to set alarms and send notifications when metrics cross predetermined values, which is very useful when you’re busy doing something else. Viewing metrics on the Amazon DocumentDB console The easiest way to view cluster- and instance-level metrics is to access the monitoring blade on the Amazon DocumentDB console. To view these, complete the following steps: On the Amazon DocumentDB console, in the navigation pane, choose Instances. From the list of instances, choose the name of the instance that you want metrics for. (To view cluster level metrics, choose Clusters. Then, from the list of clusters, choose the name of the cluster you want metrics for). In the resulting instance summary page, choose the Monitoring tab to view graphical representations of your Amazon DocumentDB instance’s metrics. Because a graph must be generated for each metric, it might take a few minutes for the CloudWatch graphs to populate. To help with organization and readability, the metrics are categorized in the following way: Resource Utilization, Throughput, Latency, Operations and System. The following image shows a screenshot of the VolumeBytesUsed and CPUUtilization metrics on the Amazon DocumentDB console. Next, let’s look at how to use CloudWatch to monitor metrics and set alarms. Viewing metrics on the CloudWatch console A more powerful tool to view metrics is through the CloudWatch console. CloudWatch is a monitoring service for virtually all AWS services, not just Amazon DocumentDB. You can use CloudWatch to detect anomalous behavior in your environments, set alarms, visualize logs and metrics side by side, take automated actions, troubleshoot issues, and discover insights to keep your applications running smoothly. To view CloudWatch metrics on the CloudWatch console, we set up a CloudWatch dashboard and populate it with metrics for storage and CPU utilization. The dashboard enables you to monitor resources in a single view and customize the display with graphs and components beyond the metrics we covered in the previous method. For more information, see Using Amazon CloudWatch Dashboards. To create the dashboard, complete the following steps: On the CloudWatch console, in the navigation pane, choose Dashboards. Choose Create dashboard. Enter a name for the dashboard. Choose Create dashboard. Select a widget type to configure (widgets are components in the dashboard and are needed to display the metric values). For this post, choose Line. Choose Next. When prompted to choose a data source, choose Metrics. Choose Configure. On the All metrics tab, select DocDB. Choose a metric dimension (for example, Cluster Metrics). Choose the VolumeBytesUsed metric.  VolumeBytesUsed is the amount of storage used by your cluster in bytes. The dashboard aggregates metrics from all clusters, so be sure to select the appropriate cluster. Choose Create widget. You should see the VolumeBytesUsed metric on your dashboard. Now we add the CPUUtilization metric to the dashboard. CPUUtilization tells us the percentage of CPU used by the cluster. Choose Add widget and repeat the previous steps, replacing the VolumeBytesUsed metric with CPUUtilization. When you’re finished, your dashboard should look similar to the following screenshot. Choose Save dashboard. Congratulations! You now have a dashboard to quickly view your cluster’s storage capacity and CPU utilization. You can also use AWS CloudFormation to provision resources quickly and consistently, and manage them throughout their lifecycles, by treating infrastructure as code. In this link you can download an example CloudFormation template to build a CloudWatch dashboard for an Amazon DocumentDB cluster. In the next section, we show how to create an alarm when one of the metrics crosses a threshold. Creating an alarm notification with CloudWatch In this section, we show how to create an alarm when the CPUUtilization metric goes above a certain threshold (for this post, 80%). We configure the alarm to email a message when this threshold is breached. To set up the alarm, do the following: On the CloudWatch console, in the navigation pane, choose Alarms. Choose Create alarm. Choose Select metric. On the All metrics tab, select DocDB. Choose a metric dimension (for example, Cluster Metrics). Find the CPUUtilization metric and choose Select metric. Enter a meaningful metric name (for this post, we keep the name as CPUUtilization). For Statistic, keep the default value (Average). Depending on what you want to measure, you could also choose Sum, Maximum, or Minimum. For Conditions, enter 80. This is our numerical threshold, which triggers the alarm whenever the CPUUtilization metric crosses 80%. Choose Next. Choose Create new topic. Enter a unique topic name (for example, email-test). For Email endpoints that will receive the notification, enter the destination email. Choose Create topic.  To subscribe to the notification, you need to check your destination email for an automated message from Amazon SNS. The email contains a link to confirm your subscription to the topic. After you confirm your subscription, you can accept automated email alerts. This feature protects end-users from receiving alerts they never signed up for. Choose Next. Enter a name and optional description. Choose Next. Review all the parameters to ensure they are correct. If you need to change anything, choose Edit. When the parameters are to your liking, choose Create alarm. Your console should look similar to the following screenshot, with a list of alarms and their status and condition. You now have a functioning alarm on the dashboard. Whenever the CPUUtilization metric crosses 80% within a 5-minute period, subscribed users receive a notification email. Additional metrics to monitor As a best practice, it’s recommended to set alarms on your overall service bill. On the CloudWatch console, choose Alarms. Choose Billing. Choose Create alarm. Follow the same process outlined in the preceding section to send a notification when the overall bill reaches 50% and 75% of your expected monthly spend. The following table summarizes several other metrics that might be useful to track. NameSpace Metric Description Recommendation Action to Take When Triggered AWS/Billing EstimatedCharges Total charges for all AWS services. Set threshold for 50% and 75% of expected monthly spend. Determine the underlying service consuming charges and reduce consumption where applicable. DocumentDB/Instance BufferCacheHitRatio The percentage of requests that are served by the buffer cache. Set alarm to under 95% for more than a 5-minute period. Consider scaling the instance vertically and replacing it with another instance containing more RAM. DocumentDB/Instance IndexBufferCacheHitRatio The percentage of index requests that are served by the buffer cache. Set alarm to under 95% for more than a 5-minute period. Consider scaling the instance vertically and replacing it with another instance containing more RAM. DocumentDB/Instance DatabaseConnections The number of connections open on an instance taken at a 1-minute frequency. 25,000 (30,000 is the maximum, which is different for every instance size). Check the application and deployment to understand why there are so many connections. Check driver configurations. Check if many containers or AWS Lambda functions have been created for some reason. DocumentDB/Instance DatabaseCursors The maximum number of open cursors on an instance in a 1-minute period. 4,000 (4,560 is the maximum, which is different for every instance size). Check that applications are properly closing cursors explicitly when they are finished with them. DocumentDB/Instance FreeableMemory The amount of available random access memory, in bytes. Under 10% over a 5-minute period. Consider scaling the instance vertically and replacing it with another instance containing more RAM. DocumentDB/Instance CPUUtilization The percentage of CPU used by an instance. Over 80% over a 5-minute period. For read-heavy workloads, consider scaling the cluster horizontally to spread the work among different read replicas. For write-heavy workloads, consider scaling the primary instance vertically. DocumentDB/Cluster DBClusterReplicaLagMaximum The maximum amount of lag, in milliseconds, between the primary instance and each Amazon DocumentDB instance in the cluster. Set alarm if replica is lagging beyond 5 seconds. Check to see if the replica instances are under stress (for example, high CPU, low available memory, or high read latency). DocumentDB/Cluster DatabaseCursorsTimedOut The number of cursors that timed out in a 1-minute period. No alarm; this is informational. Check that applications are properly closing cursors explicitly when they are finished with them. DocumentDB/Cluster VolumeBytesUsed The amount of storage used by your cluster in bytes. No alarm; this is informational. N/A DocumentDB/Cluster VolumeWriteIOPs The average number of billed write I/O operations from a cluster volume, reported at 5-minute intervals. Set an alarm on a number that is over your typical maximum. N/A DocumentDB/Cluster VolumeReadIOPs The average number of billed read I/O operations from a cluster volume, reported at 5-minute intervals. No alarm; this is informational. N/A DocumentDB/Cluster Opcounters See Monitoring Amazon DocumentDB with CloudWatch for a complete list of all opcounters metrics. No alarm; this is informational. N/A Conclusion This post walked through two methods to view cluster- and instance-level metrics. The first method uses the Amazon DocumentDB metrics blade. It’s the easiest and fastest method to view metrics directly on the console, and supports over 50 individual- and cluster-level metrics. The other method uses CloudWatch. This method is slightly more involved, but gives you more insights into the metrics, including the ability to set alarms and notifications. In future posts, we look at how to use AWS CloudTrail service to log auditing events. We also dive deeper into the Amazon DocumentDB profiler tool, which allows you to explore and debug slow running queries.

Introducing MongoDB 4.0 compatibility and Transactions in Amazon DocumentDB

Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads. Today we’re announcing compatibility with MongoDB 4.0 for Amazon DocumentDB. With this launch, you can now use atomic, consistent, isolated, and durable (ACID) transactions, open a change stream cursor for a database or cluster, and much more. For the full release notes for Amazon DocumentDB 4.0, see MongoDB 4.0 Compatibility. In this post, I summarize what’s new in Amazon DocumentDB 4.0 and show you how to get started with Amazon DocumentDB 4.0 and transactions using an AWS Cloud9 environment. What’s new in Amazon DocumentDB 4.0? The following are some of the major features and capabilities that were introduced in Amazon DocumentDB 4.0. To see a full list of the new capabilities, see MongoDB 4.0 Compatibility. ACID Transactions – Amazon DocumentDB now supports the ability to perform transactions across multiple documents, statements, collections, and databases. Transactions simplify application development by enabling you to perform ACID operations across one or more documents within an Amazon DocumentDB cluster. For more information, see Transactions. Change streams – You can now open a change stream at the cluster level (client.watch() or mongo.watch()) and the database level (db.watch()). You can also specify a startAtOperationTime to open a change stream cursor, and extend your change stream retention period to 7 days (previously, the limit was 24 hours). For more information, see Using Change Streams with Amazon DocumentDB. AWS DMS – You can now use AWS Database Migration Service (AWS DMS) to migrate your MongoDB 4.0 workloads to Amazon DocumentDB. AWS DMS now supports a MongoDB 4.0 source, Amazon DocumentDB 4.0 target, and an Amazon DocumentDB 3.6 source for performing upgrades between Amazon DocumentDB 3.6 and 4.0. For more information, see Using Amazon DocumentDB as a target for AWS Database Migration Service. Monitoring – With the addition of transactions, you can now monitor your transaction usage with five new Amazon CloudWatch metrics: TransactionsOpen, TransactionsOpenMax, TransactionsAborted, TransactionsStarted, and TransactionsCommitted, in addition to new fields in currentOp, ServerStatus, and profiler. For more information, see Monitoring Amazon DocumentDB with CloudWatch. Performance and indexing – Included in this release are multiple performance and indexing improvements: the ability to use an index with the $lookup aggregation stage, find() queries with projections can be served directly from an index (covered query), the ability to use hint() with the findAndModify API, performance optimizations for $addToSet operator, and improvements to reduce overall index sizes. For more information, see Release Notes. Operators – We have added support for new aggregation operators: $ifNull, $replaceRoot, $setIsSubset, $setInstersection, $setUnion, and $setEquals. For more information, see Supported MongoDB APIs, Operations, and Data Types. Role based access control (RBAC) – With the ListCollection and ListDatabase commands, you can now optionally use the authorizedCollections and authorizedDatabases parameters to allow users to list the collections and databases that they have permission to access without requiring the listCollections and listDatabase roles, respectively. Users can also end their own cursors without requiring the KillCursor role. For more information, see Restricting Database Access Using Role-Based Access Control (Built-In Roles). Getting started with Amazon DocumentDB 4.0 and transactions The first step is to create an AWS Cloud9 environment and an Amazon DocumentDB cluster in your default Amazon Virtual Private Cloud (Amazon VPC). For instructions on creating a default VPC, see Getting Started with Amazon VPC. This post demonstrates how to connect to your Amazon DocumentDB cluster from your AWS Cloud9 environment with a mongo shell and run a transaction. When creating AWS resources, we recommend that you follow the best practices for AWS Identity and Access Management (IAM). The following diagram shows the final architecture of this walkthrough. For this walkthrough, use the default VPC in a given Region. For more information, see Creating a Virtual Private Cloud (VPC). Creating an AWS Cloud9 environment To create your AWS Cloud9 environment, complete the following steps: On the AWS Cloud9 console, choose Create environment. Under Environment name and description, for Name, enter a name for the environment. This post enters the name DocumentDBCloud9. Choose Next step. In the Configure settings section, accept all defaults. Choose Next step. In the Review section, choose Create environment. The provisioning of the AWS Cloud9 environment can take up to 3 minutes. When it’s complete, you see a command prompt. You’re redirected to the command prompt to install the mongo shell and connect to your Amazon DocumentDB cluster. Creating a security group In this step, you use Amazon Elastic Compute Cloud (Amazon EC2) to create a new security group that enables you to connect to your Amazon DocumentDB cluster on port 27017 (the default port for Amazon DocumentDB) from your AWS Cloud9 environment. On the Amazon EC2 console, under Network & Security, choose Security groups. Choose Create security group. For Security group name, enter demoDocDB. For VPC, accept the usage of your default VPC. For Description, enter a description. In the Inbound rules section, choose Add rule. For Type, choose Custom TCP Rule. For Port Range, enter 27017.The source security group is the security group for the AWS Cloud9 environment you just created. To see a list of available security groups, enter cloud9 in the destination field. Choose the security group with the name aws-cloud9-. Accept all other defaults and choose Create security group. The following screenshot shows you the security groups that were created in this step and the AWS Cloud9 security group that was created when you created an AWS Cloud9 environment. Creating an Amazon DocumentDB 4.0 cluster To create your Amazon DocumentDB 4.0 cluster, complete the following steps: On the Amazon DocumentDB console, on the Clusters page, choose Create. For Engine version, choose the default (4.0.0). On the Create Amazon DocumentDB cluster page, for Instance class, choose t3.medium. For Number of instances, choose 1. This helps minimize costs. Leave other settings at their default. In the Authentication section, enter a username and password. Turn on Show advanced settings. In the Network settings section, for VPC security groups, choose demoDocDB. Choose Create cluster. Amazon DocumentDB is now provisioning your cluster, which can take up to a few minutes to finish. You can connect to your cluster when both the cluster and instance status show as Available. While Amazon DocumentDB provisions the cluster, complete the remaining steps to connect to your Amazon DocumentDB cluster. Installing the 4.0 mongo shell You can now install the mongo shell, which is a command-line utility that you use to connect to and query your Amazon DocumentDB cluster. On the AWS Cloud9 console, under Your environments, choose DocumentDBCloud9. Choose Open IDE. To install the 4.0 mongo shell, at the command prompt, create the repository file with the following code: echo -e "[mongodb-org-4.0] nname=MongoDB Repositorynbaseurl=https://repo.mongodb.org/yum/amazon/2013.03/mongodb-org/4.0/x86_64/ngpgcheck=1 nenabled=1 ngpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc" | sudo tee /etc/yum.repos.d/mongodb-org-4.0.repo When it’s complete, install the mongo shell with the following code: sudo yum install -y mongodb-org-shell Transport Layer Security (TLS) is enabled by default for any new Amazon DocumentDB clusters. For more information, see Managing Amazon DocumentDB Cluster TLS Settings. To encrypt data in transit, download the CA certificate for Amazon DocumentDB. See the following code: wget https://s3.amazonaws.com/rds-downloads/rds-combined-ca-bundle.pem Connecting to your Amazon DocumentDB cluster You’re now ready to connect to your Amazon DocumentDB cluster. On the Amazon DocumentDB console, on the Clusters page, locate your cluster. This post uses the cluster docdb-2020-10-09-21-45-11. Choose the cluster you created. Copy the connection string provided. Omit so that you’re prompted for the password by the mongo shell when you connect. This way, you don’t have to type your password in cleartext.Your connection string should look like the following screenshot. When you enter your password and can see the rs0:PRIMARY> prompt, you’re successfully connected to your Amazon DocumentDB cluster. For information about troubleshooting, see Troubleshooting Amazon DocumentDB. When you have connected with the mongo shell, you can discover the version (4.0.0) with the following command: db.version() You get the following output: 4.0.0 Using transactions Now that you’re connected to your cluster with the mongo shell, you can explore using transactions. One of the classic use cases for transactions is debiting money from one person’s account and crediting that money in another person’s account. Because the use case deals with two separate operations in the database, it’s desirable that the two operations run within a transaction and follow the ACID properties. For this post, we transfer $400 from Bob’s bank account to Alice’s bank account. Both accounts begin with $500. To start from with an empty collection, first drop the account collection: db.account.drop() You get the following output: {true, false} Insert data into the collection to represent Bob’s account: db.account.insert({"_id": 1, "name": "Bob", "balance": 500.00}); You get the following output: WriteResult({ "nInserted" : 1 }) Insert data into the collection to represent Alice’s account: db.account.insert({"_id": 2, "name": "Alice", "balance": 500.00}); You get the following output: WriteResult({ "nInserted" : 1 }) To start a transaction, create a session and a session object for the account: var mySession = db.getMongo().startSession(); var mySessionObject = mySession.getDatabase('test').getCollection('account'); mySession.startTransaction({readConcern: {level: 'snapshot'}, writeConcern: {w: 'majority'}}); Within the transaction, debit $400 from Bob’s account: mySessionObject.updateOne({"_id": 2}, {"$inc": {"balance": 400}}); You get the following output: { "acknowledged" : true, "matchedCount" : 1, "modifiedCount" : 1 } Similarly, credit Alice’s account with $400: mySessionObject.updateOne({"_id": 1}, {"$inc": {"balance": -400}}); You get the following output: { "acknowledged" : true, "matchedCount" : 1, "modifiedCount" : 1 } Within the transaction, you can see both updates with the following code: mySessionObject.find() You get the following output: { "_id" : 2, "name" : "Alice", "balance" : 900 } { "_id" : 1, "name" : "Bob", "balance" : 100 } If you view outside of the transaction, the updates aren’t yet visible: db.account.find() You get the following output: { "_id" : 1, "name" : "Alice", "balance" : 500 } { "_id" : 2, "name" : "Bob", "balance" : 500 } Commit the transaction and end the session: mySession.commitTransaction() mySession.endSession() To see the updates, enter the following code: db.account.find() You get the following output: { "_id" : 2, "name" : "Alice", "balance" : 900 } { "_id" : 1, "name" : "Bob", "balance" : 100 } Cleaning up When you complete the walkthrough, you can either stop your Amazon DocumentDB cluster to reduce costs or delete the cluster. By default, after 30 minutes of inactivity, your AWS Cloud9 environment stops the underlying EC2 instance to help save costs. Summary This post introduced you to MongoDB 4.0 compatibility in Amazon DocumentDB and showed you how to get started with Amazon DocumentDB 4.0 and transactions by creating an AWS Cloud9 environment, installing the mongo 4.0 shell, creating an Amazon DocumentDB cluster, connecting to your cluster, and walking through a common use case for transactions. For more information, see MongoDB 4.0 Compatibility and Transactions. For more information about recent launches and blog posts, see Amazon DocumentDB (with MongoDB compatibility) resources.
