> The current implementation of compaction uses the txn id in the directory
> name. This is used to isolate the queries from reading the directory until
> compaction has finished and to avoid the compactor marking used earlier. In
> case of replication, during bootstrap , directory is copied as it is with the
> same name from source to destination cluster. But the directory created by
> compaction with txn id can not be copied as the txn list at target may be
> different from source. The txn id which is valid at source may be an aborted
> txn at target. So conversion logic is required to create a new directory with
> valid txn at target and dump the data to the newly created directory.
