<p>Here is a list of enhancements:</p>
<p> * Move to MySQL 5.1.31</p>
<p> * Scalability fix — ability to use several rollback segments. Increasing the number of rseg may be helpful for CPU scale of write-intentional workloads.</p>

<p>Percona XtraDB 1.0.2-3 (Sapporo) available in source and several binary packages.</p>XtraDB storage engine release 1.0.2-22008-12-30T06:39:47.440600+00:002009-01-13T13:37:23.655580+00:00tag:launchpad.net,2008-12-30:/+announcement/1702Evgeniy Stepchenkohttps://launchpad.net/~evgeny-stepchenko<p>Today we announce release 1.0.2-2 of our XtraDB storage engine.</p>
<p>The source code for version 1.0.2-2 you can get as: bzr branch <a class="branch-short-link" href="https://launchpad.net/+code/percona-xtradb">lp:percona-xtradb</a> -r tag:release-1.0.2-2 percona-<wbr/>xtradb-<wbr/>1.0.2-2</p>
<p>Here is a list of enhancements:</p>
<p> * split-buffer_<wbr/>pool_mutex</p>
<p>The patch splits global InnoDB buffer_pool mutex into several and eliminates waitings on flush IO and mutex when there is no enough free buffers. It helps if you have performance drops when data does not fit in memory.</p>
<p> * innodb_<wbr/>extra_undoslots</p>
<p>InnoDB has a concurrent transaction limit of 1024 because in the standard InnoDB the number of undo slots is fixed value. This patch expands the maximum number of undo slots to 4072 and allows better utilizing modern hardware. (Thank SmugMug for this feature!)</p>
<p>ATTENTION: If the option was enabled and the expanded slots are used, you cannot use the datafile with system tablespace for the software which assume 1024 slots (e.g. the other mysqld or innodb hotbackup). See documentation for details.</p>
