Building Metadata-Driven Pipelines in Azure Data Factory
Tumblr media
1. Introduction to Metadata-Driven Pipelines
Metadata-driven pipelines in Azure Data Factory (ADF) provide a dynamic and scalable approach to orchestrating data workflows. Instead of hardcoding pipeline configurations, metadata (stored in a database or JSON file) defines:
Source & destination locations
File formats & schemas
Transformation logic
Processing rules
This approach enhances reusability, reduces maintenance efforts, and allows for seamless pipeline modifications without redeploying code.
2. Storing and Managing Metadata
Metadata can be stored in:
Azure SQL Database: Structured metadata for multiple pipelines
Azure Blob Storage (JSON/CSV files): Unstructured metadata for flexible processing
Azure Table Storage: NoSQL metadata storage for key-value pairs
For this blog, we’ll cover two practical examples:
Using a JSON file stored in Azure Blob Storage
Using a metadata table in Azure SQL Database
3. Example 1: JSON-Based Metadata in Azure Blob Storage
Step 1: Define Metadata JSON File
Create a JSON file (metadata.json) in Azure Blob Storage to define source and destination details:json{ "pipelines": [ { "pipeline_name": "CopyDataPipeline", "source": { "type": "AzureBlobStorage", "path": "source-container/raw-data/" }, "destination": { "type": "AzureSQLDatabase", "table": "ProcessedData" }, "file_format": "csv" } ] }
Step 2: Create a Lookup Activity in ADF
Add a Lookup Activity in ADF to read the JSON metadata from Azure Blob Storage.
Configure the Dataset to point to the JSON file.
Enable the First row only option if fetching a single record.
Step 3: Use Metadata in a ForEach Activity
Add a ForEach Activity to iterate over metadata records.
Inside the loop, use a Copy Activity to dynamically move data based on metadata.
Step 4: Configure Dynamic Parameters
In the Copy Activity, set dynamic parameters:
Source Dataset: @activity('Lookup').output.pipelines[0].source.path
Destination Table: @activity('Lookup').output.pipelines[0].destination.table
Now, the pipeline dynamically reads metadata and copies data accordingly.
4. Example 2: SQL-Based Metadata for Pipeline Execution
Step 1: Create Metadata Table in Azure SQL Database
Execute the following SQL script to create a metadata table:sqlCREATE TABLE MetadataPipelineConfig ( ID INT IDENTITY(1,1) PRIMARY KEY, PipelineName NVARCHAR(100), SourceType NVARCHAR(50), SourcePath NVARCHAR(255), DestinationType NVARCHAR(50), DestinationTable NVARCHAR(100), FileFormat NVARCHAR(50) );INSERT INTO MetadataPipelineConfig (PipelineName, SourceType, SourcePath, DestinationType, DestinationTable, FileFormat) VALUES ('CopyDataPipeline', 'AzureBlobStorage', 'source-container/raw-data/', 'AzureSQLDatabase', 'ProcessedData', 'csv');
Step 2: Use a Lookup Activity to Fetch Metadata
Add a Lookup Activity in ADF.
Configure the Source Dataset to point to the MetadataPipelineConfig table.
Fetch all metadata records by disabling the First row only option.
Step 3: Use ForEach Activity and Copy Activity
Add a ForEach Activity to loop over the metadata rows.
Inside the loop, configure a Copy Activity with dynamic expressions:
Source Dataset: @item().SourcePath
Destination Table: @item().DestinationTable
Step 4: Deploy and Run the Pipeline
Once the pipeline is deployed, it dynamically pulls metadata from SQL and executes data movement accordingly.
5. Benefits of Metadata-Driven Pipelines
✅ Flexibility: Modify metadata without changing pipeline logic  �� Scalability: Handle multiple pipelines with minimal effort  ✅ Efficiency: Reduce redundant pipelines and enhance maintainability
6. Conclusion
Metadata-driven pipelines in Azure Data Factory significantly improve the efficiency of data workflows. Whether using JSON files in Azure Blob Storage or structured tables in Azure SQL Database, this approach allows for dynamic and scalable automation.

SandboxEscaper is back with a new Windows Zero-Day in Win 10 Task Scheduler
The developer SandboxEscaper makes the line again, this time he publicly released the exploit code for a Windows zero-day that affect the Windows 10 Task Scheduler.
Since August 2018, the expert already revealed other four Windows zero-day vulnerabilities without reporting them to Microsoft before disclosing them to the public,
The new zero-day was disclosed a week after Microsoft as released its monthly Patch Tuesday Security updates.
Like the Windows zero-day disclosed in August, this new issue affects Microsoft Windows Task Scheduler.
SandboxEscaper demonstrated that is possible to trigger the Windows zero-day by using malformed legacy tasks (.JOB format) and importing them in the Task Scheduler utility. and they can still be added to newer versions of the operating system.
Every JOB file is imported by the Task Scheduler with arbitrary DACL (discretionary access control list) control rights.
The experts pointed out that in the absence of the DACL, the system grants any user full access to the file.
There are two folders for tasks, c:windowstasks for legacy purposes and c:windowssystem32tasks used by the task scheduler.
In the old days (i.e windows xp) tasks would be placed in c:windowstasks in the “.job” fileformat.
The researcher explains that in order to trigger the flaw it is necessary to import legacy task files into the Task Scheduler on Windows 10. This is possible copying old .job files into c:windowstasks running a command using executables ‘schtasks.exe’ and ‘schedsvc.dll’ copied from the old system, it leads to a remote procedure call (RPC) to “_SchRpcRegisterTask.” This function allows registering a task with the server exposed by the Task Scheduler service.
“If on windows 10 you want to import a .job file into the task scheduler you have to copy your old .job files into c:windowstasks and run the following command using “schtasks.exe and schedsvc.dll” copied from the old system: “schtasks /change /TN “taskname” /RU username /RP password”
(found this here: https://social.technet.microsoft.com/Forums/windowsserver/en-US/467e5cab-2368-42de-ae78-d86b644a0e71/transfer-scheduled-tasks-to-server-2008?forum=winserverMigration)
This will result in a call to the following RPC “_SchRpcRegisterTask”, which is exposed by the task scheduler service. (I assume that to trigger this bug you can just call into this function directly without using that schtasks.exe copied from windows xp.. but I am not great at reversing    )” wrote the expert.
“It starts out by impersonating the current user. But when it hits the following function:
int __stdcall tsched::SetJobFileSecurityByName(LPCWSTR StringSecurityDescriptor, const unsigned __int16 *, int, const unsigned __int16 *)
It starts impersonating itself (NT AUTHORITYSYSTEM)! And then calls SetSecurityInfo on a task it created in c:windowssystem32tasks.” he added.
Summarizing, the expert discovered that even starting with limited privileges it is possible to get SYSTEM rights by invoking a specific function. SandboxEscaper published a video PoC of the Windows zero-day that shows how to trigger it on Windows x86.
Will Dormann, vulnerability analyst at CERT/CC, confirmed that the Windows zero-day works on a fully patched (May 2019) Windows 10 x86 system.
I can confirm that this works as-is on a fully patched (May 2019) Windows 10 x86 system. A file that is formerly under full control by only SYSTEM and TrustedInstaller is now under full control by a limited Windows user. Works quickly, and 100% of the time in my testing. pic.twitter.com/5C73UzRqQk
— Will Dormann (@wdormann) May 21, 2019
Dormann was able to reproduce the issue Recompiling the code on 64-bit Windows 10 and Windows Server 2016 and 2019, only on Windows 8 and 7 it was not possible reproduce it.
Unfortunately for Microsoft, the problems are not ended here, SandboxEscaper announced at least another four Windows zero-day vulnerabilities, Three local privilege escalation (LPE) issues leading to code execution and a sandbox escape.
SandboxEscaoer wants to sell the exploits for the above issue to non-western buyers and asks the Local Privilege Escalation bugs for at least 60,000 each.
“Oh and I have 4 more unpatched bugs where that one came from. 3 LPEs (all gaining code exec as system, not lame delete bugs or whatever), and one sandbox escape.” she wrote
“If any non-western people want to buy LPEs, let me know. (Windows LPE only, not doing any other research nor interested in doing so). Won’t sell for less then 60k for an LPE.”
“I don’t owe society a single thing. Just want to get rich and give you *** in the west the middlefinger.”
Since August, SandboxEscaper has publicly dropped exploits for two Windows zero-day vulnerabilities forcing Microsoft to quickly address them to avoid its users being targeted by hackers.
In October, SandboxEscaper released the proof-of-concept exploit code for Microsoft Data Sharing that allowed a low privileged user to delete critical system files from Windows systems.
In December, she published a proof-of-concept (PoC) code for a new Windows zero-day, it is the fourth she released this year.
Stay tuned …
