Review Comment:
why only restore need refresh.
does there have follow case:
1. job start
2. schema operator received some schema change events and send it to
coordinator.
3. operator failed before schema operator get response and there have no
checkpoint.
4. schema operator restart and send new `CreateTableEvent` to the
coordinator.
5. coordinator have some pending event and cause new `CreateTableEvent` will
in the pending list, and schema operator will blocking forever.
