[Feature]: Check the catalog version in memory is consistent with that in datastore when standby node becomes to leader #398
Description
- Summary (Provide a general summary of the issue in the Title above):(required)
If catalog update operation is done on leader node (must flushed to datastore) but not sent to standby node, and then the leader role changed to standby node. At this case, the memory on standby node is expired, we should clear them. (TODO)
Also, if catalog version in memory is same with it in datastore, we should flush the data in memory to datastore when the standby node becomes to leader. (This case has been handled now.)
