> Key: FLINK-15393
> URL: https://issues.apache.org/jira/browse/FLINK-15393
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Runtime
> Affects Versions: 1.10.0
> Reporter: hailong wang
> Priority: Major
>
> In Blink planner, we use ttl state to clean expired data by rocksdb for regular joins. The StateTtlConfig is:
> {code:java}
> StateTtlConfig
> .newBuilder(Time.milliseconds(retentionTime))
> .setUpdateType(StateTtlConfig.UpdateType.OnCreateAndWrite)
> .setStateVisibility(StateTtlConfig.StateVisibility.ReturnExpiredIfNotCleanedUp)
> .build();
> {code}
> I think we should use StateTtlConfig.StateVisibility.NeverReturnExpired to prevent to join expired data.
> BTW, Only regular joins use rocksdb filter to clean expired data, should we change timer to rocksdb filter in other sql operator such as TemporalTableJoin?
