This is only for external tables. This will be before metadata copy as

> Currently the iterator used while copying table data is memory based. In case
> of a database with very large number of table/partitions, such iterator may
> cause HS2 process to go OOM.
> Also introduces a config option to run data copy tasks during repl load
> operation.
