> 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.
