Percona Server tree with support of Fusion-io atomic writes and DirectFS

 | September 24, 2012 |  Posted In: MySQL, Percona Software


Not so long ago Fusion-io announced an SDK which provides direct API access to Fusion ioMemory(tm) in addition to providing a native filesystem (directFS) with a goal to avoid overhead from kernel and regular Linux filesystems: ext4 and xfs. This requires a support from application, it should use special calls for IO. With help from Fusion-io, we provide source code of Percona Server which uses direct API access. The main idea that with this functionality you can disable “innodb-doublewrite”, retain ACID compliance by using atomic writes, and in IO intensive workloads gain an additional 30-50% in throughput when compared to workloads on the same ioMemory™ device using an unmodified Percona Server. Further benchmarking results on latency variability reduction expected soon.
Percona Server 5.5.27 with Fusion-io atomic writes is available from Launchpad repository: lp:~percona-core/percona-server/percona-server-5.5.27-fusion-io-atomic,
and the patch itself is the revision 300.
To compile it you need access to Fusion-io SDK, which is currently available to early-access partners prior to general release. Contact Fusion-io at developer.fusionio.com for details, or speak with Fusion-io in New York at their Percona Live! presentation.
