Gluster now has the changelog translator (journaling mechanism) which
records
changes made to the filesystem (on each brick).
In which version will that be included? 3.5? And is there any
documentation on performance of journal Geo-Rep vs. old Geo-Rep?
Yes, changelog will be part of 3.5.
Performance of the new journal based geo-rep should be better than old
geo-rep due to these improvements:
- Easier identification of changes by querying changelog
- Parallel geo-replication which utilizes multiple nodes on the master &
slave for data replication. The earlier implementation had a single
channel through which replication would happen.
Running performance tests during the community test day for 3.5 might be
helpful in determining the performance gain with parallel changelog
based geo-replication.
