------------------------------------
Summary: 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
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.
