The Truncate Table orchestration component removes all rows from a table or partitions, while keeping the table intact. The table must not be a view or an external or temporary table.

Truncate is implemented in two different ways, depending on whether the current flow is in the middle of a database transaction or not. The first is by using a `TRUNCATE` statement. For more information, read [TRUNCATE TABLE for Snowflake](https://docs.snowflake.com/en/sql-reference/sql/truncate-table.htm), [TRUNCATE TABLE for Databricks](https://docs.databricks.com/en/sql/language-manual/sql-ref-syntax-ddl-truncate-table.html), and [TRUNCATE for Redshift](https://docs.aws.amazon.com/redshift/latest/dg/r_TRUNCATE.html), respectively. The second is by using a `DELETE FROM` statement, which is preferable if the current pipeline is using a transaction. For more information, read [DELETE FROM for Snowflake](https://docs.snowflake.com/en/sql-reference/sql/delete.html), [DELETE FROM for Databricks](https://docs.databricks.com/en/sql/language-manual/delta-delete-from.html), and [DELETE for Redshift](https://docs.aws.amazon.com/redshift/latest/dg/r_DELETE.html), respectively.

* A truncate operation is faster than a delete operation.
* A truncate operation is not transaction safe—it cannot be rolled back.
