WDR Snapshot Schema

After the WDR snapshot function is enabled (enable_wdr_snapshot is set to on), objects are created in schema snapshot in user tablespace pg_default in database postgres to flush WDR snapshot data. By default, the initial user or users with the monadmin permission can access objects in the snapshot schema.

You can set the parameter wdr_snapshot_retention_days to automatically manage the snapshot lifecycle.

Do not add, delete, or modify tables in the snapshot schema. Manual modification or damage to these tables may cause WDR exceptions or even WDR unavailability.
