> This Jira is to track the improvement for the above code review comment.
> The batching logic of the RELOAD event needs to be improved in a way that
> certain events (events that require table reload) of the same table can be
> skipped, as the current reload event will essentially reload the table.
> Events can only be skipped:
> 1) The same partitions that occur in the current RELOAD event were the same
> ones that are modified previously,
> 2) The current reload event is a table-level event.
