> In replication load, both add partition and insert operations are handled
> through import. Import creates 3 major tasks. Copy, add partition and move.
> Copy does the copy of data from source location to staging directory. Then
> add partition (which runs in parallel to copy) creates the partition in meta
> store. Its a no op in case of insert and by the time this ddl task is
> executed for insert partition would be already present. The third operation
> is move. Which actually moves the file from staging directory to actual
> location. And then in case of insert it adds the insert event to notification
> table. It does this for add partition operation which is redundant as the
> event for add partition would have been written already by ddl task. With the
> optimization to copy directly to actual table location in S3, move task can
> be avoided for add partition operation replay and replay of insert need not
> create the add partition (ddl) task.
