WDR Snapshot Schema

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

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

NOTICE: 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.
