Azure Data Factory (ADF) is a cloud ETL tool developed by Microsoft. It allows you to build complex ETL pipelines using drag&drop web UI.

This article describes abilities and limitations of Azure Data Factory Dataedo connector and walk you through the import process.

Supported elements and metadata

Objects imported

  • Pipelines
    • Name
    • Folder (as schema)
    • Activities
      • Name
      • Data lineage (object and column level, details below)
  • Datasets
    • Name
    • Folder (as schema)
    • Columns (if linked service is imported to Dataedo)

Dataedo imports all the activities as data processes within pipelines. Nested activities like ForEach, Until, IfCondition, and Switch are also imported with all the activities inside them.

Activites we build automatic data-lineage for

  • Copy activity - Object-level and column-level lineage
  • Dataflow - Object-level lineage

Automatic data lineage

Dataedo ADF connector always creates automatic data lineage dataset -> task -> dataset. We also support source -> dataset -> task -> dataset -> sink for following linked service types:

  • Microsoft SQL Server
  • Azure SQL Server
  • Azure Synapse Analytics
  • Azure Blob Storage
  • Azure Data Lake Storage
  • Amazon S3,
  • Postgres

Permissions

To list resource groups in a connection window you must belong to the Data Factory Contributor role at the Resource Group level or above.

To run import you need just read access to the factory you want to document (Microsoft.DataFactory/factories/read). However in this case you must provide the resource group and factory name by hand instead of picking from the list.
