  • SourceConnection - (Required) Source connection to use.

  • ExtractQuery - (Required) SQL query to extract data from the source database.

  • TargetConnection - (Optional) Target connection to use.

  • DataLakeSystemFolder - (Required) Name of the folder in the Data Lake that acts as the parent folder for all datasets belonging to this System.

  • DataLakeDatasetFolder - (Required) Name of the folder in the Data Lake that the dataset will be stored under. Used with 'Data Lake System Folder' to form the fully qualified path to the dataset within the data Container in the Data Lake.

  • ElevateToDelta - (Optional) Ingest directly to Lakehouse Table

  • DeltaSchemaName - (Optional) The name of the Schema this transformation lives in. Required if Copy to Lakehouse Table is enabled.

  • DeltaTableName - (Optional) The name of the Lakehouse Table representing this transformation. Required if Copy to Lakehouse Table is enabled.

  • ExtractControlQuery - (Optional) For incremental loads only, a SQL query to get a 'high-water' mark for extract control.
