A human-readable name for the component.
Select a Databricks Unity Catalog. The special value [Environment Default] uses the catalog defined in the environment. Selecting a catalog will determine which databases are available in the next parameter. The Databricks schema. The special value [Environment Default] uses the schema defined in the environment. Read Create and manage schemas to learn more. The retention threshold. The default is 7, with the unit specified in Retention Unit.
Select the unit of the Retention Period. Options are Day, Hour, or Week. The default is Day.

Select the table schema. The special value [Environment Default] uses the schema defined in the environment. For more information on using multiple schemas, read Schemas. Select tables to vacuum.Only one vacuum may be running at any one time across an entire Amazon Redshift cluster. Therefore, vacuums may fail due to concurrent workloads. This is usually harmless if the same tables will be vacuumed again on the next run of the pipeline. If this is the case, consider joining the “Failure” link of the component to an End Success component to prevent vacuum failure from failing the whole pipeline. The component reclaims disk space occupied by deleted rows in a table, using the method selected here:
- None: A default vacuum operation. This is analogous to “FULL” in the current AWS implementation.
- FULL: Is equivalent to DELETE ONLY if the target table is more than 95% sorted, otherwise will perform a full sort.
- SORT ONLY: Sorts the table but does not reclaim disk space. Is quick at the expense of unclaimed memory.
- DELETE ONLY: Will not sort tables and is consequently quicker than other methods.
- REINDEX: Analyzes interleaved sort keys and performs a FULL sort.
