> Add support for state TTL.
> --------------------------
>
> Key: FLINK-17644
> URL: https://issues.apache.org/jira/browse/FLINK-17644
> Project: Flink
> Issue Type: Improvement
> Components: Stateful Functions
> Reporter: Igal Shilman
> Assignee: Igal Shilman
> Priority: Major
>
> The DataStream API supports[state TTL|[https://ci.apache.org/projects/flink/flink-docs-stable/dev/stream/state/state.html#state-time-to-live-ttl]], and it can be made accessible to stateful functions users.
> To facilitate uses cases as described in [http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Window-processing-in-Stateful-Functions-td34966.html]
>
> The proposed approach would extend the PersistedValue, PersistedTable and PersistedBuffer
> with another constructor that accepts ExpireAfter object
> which has:
> * java time duration
> * refresh on read (boolean)
> (we should never return an expired entry)
> In addition, we need to extend the remote function state to support state expiration.
