`SNAP_ID`	`NUMBER`	`NOT NULL`	Unique snapshot ID
`DBID`	`NUMBER`	`NOT NULL`	Database ID of the snapshot
`INSTANCE_NUMBER`	`NUMBER`	`NOT NULL`	Instance number of the snapshot
`SIZE_FOR_ESTIMATE`	`NUMBER`	`NOT NULL`	Pool size for the estimate (in megabytes)
`SIZE_FACTOR`	`NUMBER`		Size factor with respect to the current pool size
`ESTD_SPILL_COUNT`	`NUMBER`		Estimated count of messages spilled from the Streams pool
`ESTD_SPILL_TIME`	`NUMBER`		Estimated elapsed time (in seconds) to spill
