Multi-threaded slave: it's in!

I am very happy to share with you all that the much awaited feature request - multi-threaded slave (MTS) - has made it to the development tree targeting 5.6 release and is part of this latest 5.6 DMR release (5.6 DMR2).

I would like to take a moment to thank those of you that took the time to evaluate and provide invaluable feedback. Some started as early as the very first snapshot that was put out in the open. Part of this feedback is directly responsible for many changes, as outlined in my previous posts about MTS. Since the last snapshot, we kept on taking your suggestions seriously and improved the implementation by deploying a few of them in time for this release. Again, thanks!

What comes next for MTS? Well, it will continue to be debugged and get its overall quality improved.

What comes next for MySQL replication? You already know that we are working on the binlog group commit (by the way, you can get a hold of the second labs snapshot for that one). But, wait, there's more! We are also spending time and effort to implement another much awaited feature: Global Transaction Ids. I think you'll enjoy that one very much (there is also a very early access labs snapshot that you can check out - I'll blog about the details later on...).

Lots of interesting stuff going on. Stay tuned!

In the meantime, you can download 5.6 DMR2 and check out our labs releases.
