Percona Toolkit

Percona is glad to announce the release of Percona Toolkit 2.2.5 on October 17th, 2013 (Downloads are available here and from the Percona Software Repositories). This release is the current GA (Generally Available) stable release in the 2.2 series.

New Features:

  • Query_time histogram has been added to the pt-query-digest JSON output, not the actual chart but the values necessary to render the chart later, so the values for each bucket.
  • As of pt-table-checksum 2.2.5, skipped chunks cause a non-zero exit status. An exit status of zero or 32 is equivalent to a zero exit status with skipped chunks in previous versions of the tool.
  • New --no-drop-triggers option has been implemented for pt-online-schema-change in case users want to rename the tables manually, when the load is low.
  • New --new-table-name option has been added to pt-online-schema-change which can be used to specify the temporary table name.

Bugs Fixed:

All of Percona‘s software is open-source and free, all the details of the release can be found in the release notes and 2.2.5 milestone at Launchpad. Bugs can be reported on the Percona Toolkit launchpad bug tracker.

[UPDATE: 2013-10-23] New packages have been pushed to repositories in order to remove the unnecessary files and update the changelog.
