[PR] [FLINK-34389][autoscaler] JdbcAutoscalerStateStore explicitly writes update_time [flink-kubernetes-operator]

["1996fanrui (via GitHub)" <gi...@apache.org>]

1996fanrui opened a new pull request, #771:
URL: https://github.com/apache/flink-kubernetes-operator/pull/771

   
   ## What is the purpose of the change
   
   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.
