Starting with this release, we introduce a new release model for Percona Server. From now on, we will have both Stable and Release Candidate releases. Release Candidates will introduce new features not yet available in Stable releases.
Along with new features, our new 5.1.49-12.0 RC contains a couple of patches from the Facebook-MySQL tree – https://launchpad.net/mysqlatfacebookÂ . Of particular note is better integration with FlashCache.
We also introduce the very interesting new feature calledÂ “Permanent InnoDB Buffer Pool”Â (sponsored by a Well Known Social Network site). ItÂ allows you to keep the InnoDB buffer pool in memory between restarts of MySQL servers.
This can result in a significant decrease in warmup time after MySQL restarts.
Starting with this release, we will also provide special builds optimized for Cisco UCS B250/C250 servers, which come with a lot of memory (up to 384GB). Mentioned above, “Permanent InnoDB Buffer Pool” is especially interesting for servers with 128GB+ memory sizes, as it currently can take hours to warm up an empty InnoDB buffer pool on these boxes.
Percona Server version 5.1.49-rel12.0 RC is available for download now.
The changes in this release include:
