Rui Fan updated FLINK-34389:
----------------------------
Description:
JdbcAutoscalerStateStore explicitly writes update_time instead of relying on
the database to update.
Some databases doesn't support update the timestamp column automatically. For
example, Derby doesn't support update the update_time automatically when we
update any data. It's hard to do a general test during I developing the test
for JdbcAutoscalerEventHandler.
As the common&open source service, in order to support all databases well, it's
better to handle it inside of the service.
In order to unify the design for JdbcAutoscalerEventHandler and
JdbcAutoscalerStateStore, we update the design of JdbcAutoscalerStateStore in
this JIRA.
