-Transient tables are used to hold transitory data that does not require a data protection or recovery mechanism. Dataebend does not hold historical data for a transient table so you will not be able to query from a previous version of the transient table with the Time Travel feature, for example, the [AT](./../../20-query-syntax/dml-at.md) clause in the SELECT statement will not work for transient tables.

 Transient tables help save your storage expenses because they do not need extra space for historical data compared to non-transient tables. See [example](#create-transient-table-1) for detailed explanations.

 Databend automatically creates table snapshots upon data updates. A snapshot represents a version of the table's segment metadata.
 
-When working with Databend, you're most likely to access a snapshot with the snapshot ID when you retrieve and query a previous version of the table's data with the [AT](../../20-query-syntax/dml-at.md) clause.

 A snapshot is a JSON file that does not save the table's data but indicate the segments the snapshot links to. If you run [FUSE_SNAPSHOT](../../../15-sql-functions/111-system-functions/fuse_snapshot.md) against a table, you can find the saved snapshots for the table.
