> Key: FLINK-27085
> URL: https://issues.apache.org/jira/browse/FLINK-27085
> Project: Flink
> Issue Type: Sub-task
> Components: Table Store
> Affects Versions: 0.1.0
> Reporter: Caizhi Weng
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.1.0
>
>
> Currently we retain at least 1 snapshot when expiring. However consider the
> following scenario:
> A user writes a snapshot one day ago. Today he is reading this snapshot and
> meanwhile writing more records. If a new snapshot is created and the reading
> is not finished, the old snapshot created one day ago will be removed as it
> exceeds maximum retaining time. This will cause the reading to fail.
> We should introduce {{snapshot.num-retained.min}} to at least retain a
> minimum number of snapshots to avoid this problem.
