Guide for setting Fabric Data Factory Pipeline

The EP contains 2 load templates:

1. wsl_fabric_pyscript_load will support load for Database, OneLake and traditional file parser.
2. wsl_fabric_pyscript_load_df template is for FDF and does not support XML and JSON file in this release.

Fabric Data Factory Guide using load_df template:

In Fabric Data Factory, currently only OneLake sources are supported. When creating a connection to browse files, the Lakehouse name must be specified in the source connection. After browsing the connection and selecting a file, dragging the table will automatically populate the source properties. 
Two additional extended properties are specifically available for pipelines: “Recreate Pipeline on run” and “Pipeline Timeout Duration.”
Setting “Recreate Pipeline on run” to “True” ensures that a new pipeline is created each time the job is executed, with any existing pipeline with same name being deleted beforehand. If set to “False,” the existing pipeline remains intact, and only the execution is performed. However, if a pipeline fails  due to a data type issue or any other property-related problem, the pipeline must be deleted and recreated, as the pipeline's JSON code cannot be modified when the “Recreate Pipeline on run” property is set to “False”. The default to this property is set to “True” in the script.
Whenever the Pipeline is created and data is loaded to the table, changing the Extended property to “False” will keep that existing pipeline as it is and act as a starting point for other operations which can be done.

The second property, “Pipeline Timeout Duration,” is responsible for monitoring the pipeline once it is executed. By default, the timeout is set to 120 minutes in script. If the execution exceeds this duration, the pipeline will continue running in the background, but RED will notify the user that the  pipeline is still in progress. At this point, the user can monitor the pipeline through the Fabric portal. 

It’s important to note that even if the timeout is set to 120 minutes, if the job completes in a shorter time—such as within a minute or two—RED will mark the job as successful and display the result in the result pane accordingly

There can be issues with data types when loading data through Fabric Data Factory.In such cases, the Fabric pipeline will display an error, suggesting using varchar(8000) for the affected column (e.g., “”). The user should update the column’s data type to match the recommendation from Data Factory.After making the changes, the table should be recreated, the script regenerated,and the pipeline executed again with the extended property “Recreate Pipeline on run” set to “True” or left blank.
