It would be nice if pre-allocated binlog files were possible, but performance results from ext-3 overstates the benefit to be had. If you care about performance with the binlog enabled then don't use ext-3: http://www.facebook.com/note.php?note_id=194501560932
Not surprising, however in many environments deployments get stuck with ext3, so I do think there's benefit for the real world.
Arjen, The question isn't whether this has a real world benefit. Lots of changes do. The question is whether this is worth the effort to fix given the many other problems that could be fixed and who is going to fund that fix. This is a big change to replication internals. -- Mark Callaghan mdcallag@gmail.com
