Integrated Azure Data Lake Storage data

After you have synchronized the data, the integration of the Azure Data Lake Storage file system is completed, and the resulting assets are available in the domain that was specified in the crawler.

Warning Do not move the assets to another domain. Doing so may lead to errors during future synchronizations.

Tip ADLS synchronization relies on UUIDs.

Note In case of a partial synchronization caused by a temporary communication issue, the status of the assets that cannot be synchronized is set to Missing from source. Their previous status is restored, if they are found in the source system during the next fully successful synchronization.

By default, the assets are shown in a plain list, but you can enable a multi-path hierarchy to show it in a tree structure. The resulting assets depend on whether you use Microsoft Purview.

Synchronization results without Microsoft Purview

For the best result, use the following relations when you define a multi-path hierarchy:

• File Storage contains File Container
• File Container contains File Container
• Directory contains Directory
• File Container contains File

Synchronization results with Microsoft Purview

For the best result, use the following relations when you define a multi-path hierarchy:

• File Storage contains File Container
• File Container contains File Container
• Directory contains Directory
• File Container contains File
• File contains Table
• Table contains Column

Synchronized metadata per asset type

This table shows the metadata for each ADLS asset type.

	Technical Data Type Tip  For columns that have a structured technical data type, Array or Struct, you can click the More button in the Column asset to see the structure of the data in a dialog box. You see the technical data type in the Technical Data Type field in the At a Glance sidebar of the Column asset. For columns that have a structured technical data type, Array or Struct, click the data type name to see the structure of the data in a dialog box. This is supported for AVRO, CSV, JSON, ORC, PARQUET, PSV, SSV, TSV, TXT, and XML. In the capability settings, you can define the maximum level you want to see in the structure.
