> For REPL LOAD operations that includes both metadata and data changes should follow the
below rule.
> 1. Copy the metadata excluding the last repl ID.
> 2. Copy the data files
> 3. If Step 1 and 2 are successful, then update the last repl ID of the object.
> This rule will allow the the failed events to be re-applied by REPL LOAD and ensures
no data loss due to failures.
