Percona Toolkit 3.0.4 is Now Available

Percona Server for MongoDB

Percona ToolkitPercona announces the release of Percona Toolkit 3.0.4 on August 2, 2017.

Percona Toolkit is a collection of advanced command-line tools that perform a variety of MySQL and MongoDB server and system tasks too difficult or complex for DBAs to perform manually. Percona Toolkit, like all Percona software, is free and open source.

You download Percona Toolkit packages from the web site or install from official repositories.

This release includes the following changes:

New Features

  • PT-90: Added collection of information about prepared statements by pt-stalk when Performance Schema is enabled. For more information, see #1642750.
  • PT-91: Added the --preserve-triggers option for pt-online-schema-change to support AFTER triggers.
  • PT-138: Added --output-format option for pt-mongodb-summary to choose between JSON format and the default plain text.
  • PT-141: Added the --output-format=csv parameter for pt-archiver to archive rows in CSV format.
  • PT-142: Added the --only-same-schema-fks option for pt-online-schema-change to check foreigns keys only on tables with the same schema as the original table. This should speed up the tool’s execution, but keep in mind that if you have foreign keys referencing tables in other schemas, they won’t be detected. For more information, see #1690122.
  • PT-153: Added the --check-unique-key-change option for pt-online-schema-change to abort if the specified statement for --alter is trying to add a unique index. This is supposed to avoid adding duplicate keys that might lead to silently losing data.
  • PT-173: Added the --truncate-replicate-table option for pt-table-checksum to ensure stale data is removed.

Bug fixes

  • PT-136: Fixed pt-table-checksum to support tables that have columns with different collations or charsets. For more information, see #1674266.
  • PT-143: Fixed primary key handling by pt-archiver. For more information, see #1691630.
  • PT-144: Limited constraint name in the new table when running pt-online-schema-change. For more information, see #1491674.
  • PT-146: Fixed the --no-check-binlog-format option for pt-table-checksum to work as expected.
  • PT-148: Fixed the use of uninitialized value in printf() for pt-online-schema-change. For more information, see #1693614.
  • PT-151: Fixed pt-table-sync to prevent field type point to be taken as decimal.
  • PT-154: Reverted PT-116 to remove the --use-insert-ignore option from pt-online-schema-change.
  • PT-161: Fixed the --skip-check-slave-lag feature for pt-table-checksum to safely check for undefined values.
  • PT-178: Fixed regression in --check-slave-lag option for pt-online-schema-change.
  • PT-180: Fixed regression in --skip-check-slave-lag option for pt-online-schema-change.
  • PT-181: Fixed syntax error in pt-online-schema-change.

Other Improvements

Platform End of Life (EOL) Announcement for RHEL 5 and Ubuntu 12.04 LTS

End of Life

End of LifeUpstream platform vendors have announced the general end of life (EOL) for Red Hat Enterprise Linux 5 (RHEL 5) and its derivatives, as well as Ubuntu 12.04 LTS. With this announcement comes some implications to support for Percona software running on these operating systems.

RHEL 5 was EOL as of March 31st, 2017 and Ubuntu 12.04 LTS was end of life as of April 28th, 2017. Pursuant to our end of life policies, we are announcing that these EOLs will go into effect for Percona software on August 1st, 2017. As of this date, we will no longer be producing new packages, binary builds, hotfixes, or bug fixes for Percona software on these platforms.

We generally align our platform end of life dates with those of the upstream platform vendor. The platform end of life dates are published in advance on our website under the page Supported Linux Platforms and Versions.

Per our policies, Percona will continue to provide operational support for your databases on EOLed platforms. However, we will be unable to provide any bug fixes, builds or OS-level assistance if you encounter an issue outside the database itself.

Each platform vendor has a supported migration or upgrade path to their next major release.  Please reach out to us if you need assistance in migrating your database to your vendor’s supported platform – Percona will be happy to assist you.
