[Fabric] Dataflows Gen2 destino “archivos” - Opción 2

Continuamos con la problematica de una estructura lakehouse del estilo “medallón” (bronze, silver, gold) con Fabric, en la cual, la herramienta de integración de datos de mayor conectividad, Dataflow gen2, no permite la inserción en este apartado de nuestro sistema de archivos, sino que su destino es un spark catalog. ¿Cómo podemos utilizar la herramienta para armar un flujo limpio que tenga nuestros datos crudos en bronze?

Veamos una opción más pythonesca donde podamos realizar la integración de datos mediante dos contenidos de Fabric

Como repaso de la problemática, veamos un poco la comparativa de las características de las herramientas de integración de Data Factory dentro de Fabric (Feb 2024)

Si nuestro origen solo puede ser leído con Dataflows Gen2 y queremos iniciar nuestro proceso de datos en Raw o Bronze de Archivos de un Lakehouse, no podríamos dado el impedimento de delimitar el destino en la herramienta.

Para solucionarlo planteamos un punto medio de stage y un shortcut en un post anterior. Pueden leerlo para tener más cercanía y contexto con esa alternativa.

Ahora vamos a verlo de otro modo. El planteo bajo el cual llegamos a esta solución fue conociendo en más profundidad la herramienta. Conociendo que Dataflows Gen2 tiene la característica de generar por si mismo un StagingLakehouse, ¿por qué no usarlo?. Si no sabes de que hablo, podes leer todo sobre staging de lakehouse en este post.

Ejemplo práctico. Cree dos dataflows que lean datos con "Enable Staging" activado pero sin destino. Un dataflow tiene dos tablas (InternetSales y Producto) y otro tiene una tabla (Product). De esa forma pensaba aprovechar este stage automático sin necesidad de crear uno. Sin embargo, al conectarme me encontre con lo siguiente:

Dataflow gen2 por defecto genera snapshots de cada actualización. Los dataflows corrieron dos veces entonces hay 6 tablas. Por si fuera aún más dificil, ocurre que las tablas no tienen metadata. Sus columnas están expresadas como "column1, column2, column3,...". Si prestamos atención en "Files" tenemos dos models. Cada uno de ellos son jsons con toda la información de cada dataflow.

Muy buena información pero de shortcut difícilmente podríamos solucionarlo. Sin perder la curiosidad hablo con un Data Engineer para preguntarle más en detalle sobre la información que podemos encontrar de Tablas Delta, puesto que Fabric almacena Delta por defecto en "Tables". Ahi me compartió que podemos ver la última fecha de modificación con lo que podríamos conocer cual de esos snapshots es el más reciente para moverlo a Bronze o Raw con un Notebook. El desafío estaba. Leer la tabla delta más reciente, leer su metadata en los json de files y armar un spark dataframe para llevarlo a Bronze de nuestro lakehouse. Algo así:

Si apreciamos las cajas con fondo gris, podremos ver el proceso. Primero tomar los datos con Dataflow Gen2 sin configurar destino asegurando tener "Enable Staging" activado. De esa forma llevamos los datos al punto intermedio. Luego construir un Notebook para leerlo, en mi caso el código está preparado para construir un Bronze de todas las tablas de un dataflow, es decir que sería un Notebook por cada Dataflow.

¿Qué encontraremos en el notebook?

Para no ir celda tras celda pegando imágenes, puede abrirlo de mi GitHub y seguir los pasos con el siguiente texto.

Trás importar las librerías haremos los siguientes pasos para conseguir nuestro objetivo.

1- Delimitar parámetros de Onelake origen y Onelake destino. Definir Dataflow a procesar.

Podemos tomar la dirección de los lake viendo las propiedades de carpetas cuando lo exploramos:

La dirección del dataflow esta delimitado en los archivos jsons dentro de la sección Files del StagingLakehouse. El parámetro sería más o menos así:

Files/models$50a92467_002D7193_002D4445_002D8ac5_002D00143959ff98/*.json

2- Armar una lista con nombre de los snapshots de tablas en Tables

3- Construimos una nueva lista con cada Tabla y su última fecha de modificación para conocer cual de los snapshots es el más reciente.

4- Creamos un pandas dataframe que tenga nombre de la tabla delta, el nombre semántico apropiado y la fecha de modificación

5- Buscamos la metadata (nombre de columnas) de cada Tabla puesto que, tal como mencioné antes, en sus logs delta no se encuentran.

6- Recorremos los nombre apropiados de tabla buscando su más reciente fecha para extraer el apropiado nombre del StagingLakehouse con su apropiada metadata y lo escribimos en destino.

Para más detalle cada línea de código esta documentada.

De esta forma llegaríamos a construir la arquitectura planteada arriba. Logramos así construir una integración de datos que nos permita conectarnos a orígenes SAP, Oracle, Teradata u otro onpremise que son clásicos y hoy Pipelines no puede, para continuar el flujo de llevarlos a Bronze/Raw de nuestra arquitectura medallón en un solo tramo. Dejamos así una arquitectura y paso del dato más limpio.

Por supuesto, esta solución tiene mucho potencial de mejora como por ejemplo no tener un notebook por dataflow, sino integrar de algún modo aún más la solución.

[Fabric] Leer y escribir storage con Databricks

Muchos lanzamientos y herramientas dentro de una sola plataforma haciendo participar tanto usuarios técnicos (data engineers, data scientists o data analysts) como usuarios finales. Fabric trajo una unión de involucrados en un único espacio. Ahora bien, eso no significa que tengamos que usar todas pero todas pero todas las herramientas que nos presenta.

Si ya disponemos de un excelente proceso de limpieza, transformación o procesamiento de datos con el gran popular Databricks, podemos seguir usándolo.

En posts anteriores hemos hablado que Fabric nos viene a traer un alamacenamiento de lake de última generación con open data format. Esto significa que nos permite utilizar los más populares archivos de datos para almacenar y que su sistema de archivos trabaja con las convencionales estructuras open source. En otras palabras podemos conectarnos a nuestro storage desde herramientas que puedan leerlo. También hemos mostrado un poco de Fabric notebooks y como nos facilita la experiencia de desarrollo.

En este sencillo tip vamos a ver como leer y escribir, desde databricks, nuestro Fabric Lakehouse.

Para poder comunicarnos entre databricks y Fabric lo primero es crear un recurso AzureDatabricks Premium Tier. Lo segundo, asegurarnos de dos cosas en nuestro cluster:

Utilizar un policy "unrestricted" o "power user compute"

2. Asegurarse que databricks podría pasar nuestras credenciales por spark. Eso podemos activarlo en las opciones avanzadas

NOTA: No voy a entrar en más detalles de creación de cluster. El resto de las opciones de procesamiento les dejo que investiguen o estimo que ya conocen si están leyendo este post.

Ya creado nuestro cluster vamos a crear un notebook y comenzar a leer data en Fabric. Esto lo vamos a conseguir con el ABFS (Azure Bllob Fyle System) que es una dirección de formato abierto cuyo driver está incluido en Azure Databricks.

La dirección debe componerse de algo similar a la siguiente cadena:

oneLakePath = 'abfss://myWorkspaceId@onelake.dfs.fabric.microsoft.com/myLakehouse.lakehouse/Files/'

Conociendo dicha dirección ya podemos comenzar a trabajar como siempre. Veamos un simple notebook que para leer un archivo parquet en Lakehouse Fabric

Gracias a la configuración del cluster, los procesos son tan simples como spark.read

Así de simple también será escribir.

Iniciando con una limpieza de columnas innecesarias y con un sencillo [frame].write ya tendremos la tabla en silver limpia.

Nos vamos a Fabric y podremos encontrarla en nuestro Lakehouse

Así concluye nuestro procesamiento de databricks en lakehouse de Fabric, pero no el artículo. Todavía no hablamos sobre el otro tipo de almacenamiento en el blog pero vamos a mencionar lo que pertine a ésta lectura.

Los Warehouses en Fabric también están constituidos con una estructura tradicional de lake de última generación. Su principal diferencia consiste en brindar una experiencia de usuario 100% basada en SQL como si estuvieramos trabajando en una base de datos. Sin embargo, por detras, podrémos encontrar delta como un spark catalog o metastore.

El path debería verse similar a esto:

path_dw = "abfss://WorkspaceName@onelake.dfs.fabric.microsoft.com/WarehouseName.Datawarehouse/Tables/dbo/"

Teniendo en cuenta que Fabric busca tener contenido delta en su Spark Catalog de Lakehouse (tables) y en su Warehouse, vamos a leer como muestra el siguiente ejemplo

Ahora si concluye nuestro artículo mostrando como podemos utilizar Databricks para trabajar con los almacenamientos de Fabric.
