WDR Snapshot Data Table
The naming rule of a WDR snapshot data table is snap_{source data table}.
The source of WDR snapshot data tables is the view under DBE_PERF Schema. After the WDR snapshot function is enabled (the GUC parameter enable_wdr_snapshot is set to on), the WDR snapshot data table is created.
The initial user or monitor administrator has the permission to view the WDR snapshot data table.
