Github user fhueske commented on the issue:

    Hi @sunjincheng121, I like the idea of using `MapState` because we do not need to deserialize
and serialize the Rows when updating the state as in case of a `ValueState` or `ListState`
but just the Long timestamps to identify the Row to retract which should be OK.

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
