           How should I select the structure type of my destination table in the Synapse dedicated SQL pool?
         answer: |
           You can refer to [Indexing tables - Azure Synapse Analytics | Microsoft Docs](../sql-data-warehouse/sql-data-warehouse-tables-index.md) to understand the three options for table structure type. When clustered columnstore index is chosen, data type with max length (eg. VARCHAR(MAX)) is not supported.

+          Do I need to clean up data in the landing zone?
+        answer: |
+          No. There is a background thread that removes committed files after around 24 hours as long as the link is continuously running. In case the link is paused (coming soon) the cleanup process is also paused until it is resumed. When the link is stopped then the entire landing zone folder is removed.
