SNAPSHOT.SNAPSHOT

SNAPSHOT records the index information, start time, and end time of WDR snapshots stored in the current system. The result can be queried only in the system database but cannot be queried in the user database. After the WDR snapshot function is enabled (the GUC parameter enable_wdr_snapshot is set to on), the table is created.

**Table 1** SNAPSHOT attributes
Name	Type	Description	Example
snapshot_id	bigint	WDR snapshot ID	1
start_ts	timestamp	Start time of a WDR snapshot	2019-12-28 17:11:27.423742+08
end_ts	timestamp	End time of a WDR snapshot	2019-12-28 17:11:43.67726+08
version	int	Version of a WDR snapshot	1
