> When SchemaOperator receive SchemaChangeEvent, it will send request to SchemaRegistry and wait for applying this SchemaChangeEvent to external system synchronously.
> However, if this process take too long time, it will cause RPC TimeoutException, and During the process of task recovery, there may be other errors like `AddColumnEvent is already existed`.
