> For external tables replication, the data gets copied as separate task based
> on data locations listed in _external_tables_info file in the dump. So,
> individual events such as ADD_PARTITION or INSERT on the external tables
> should avoid copying data. So, it is enough to create table/add partition DDL
> tasks. COPY and MOVE tasks should be skipped.
