v2.2.16 released 2015-11-09 Percona Toolkit 2.2.16 has been released. This release contains 3 new features and 2 bug fixes. New Features: 1491261: When using MySQL 5.6 or later, and innodb_stats_persistent option is enabled (by default, it is enabled), then pt-online-schema-change will now run with the --analyze-before-swap option. This ensures that queries continue to use correct execution path, instead of switching to full table scan, which could cause possible downtime. If you do not want pt-online-schema-change to run ANALYZE on new tables before the swap, you can disable this behavior using the --no-analyze-before-swap option. 1402051: pt-online-schema-change will now wait forever for slaves to be available and not be lagging. This ensures that the tool does not abort during faults and connection problems on slaves. 1452895: pt-archiver now issues ‘keepalive’ queries during and after bulk insert/delete process that takes a long time. This keeps the connection alive even if the innodb_kill_idle_transaction variable is set to a low value. Bug Fixes: 1488685: The --filter option for pt-kill now works correctly. 1494082: The pt-stalk tool no longer uses the -warn option when running find, because the option is not supported on FreeBSD. Changelog Fixed bug 1452895: pt-archiver dies with “MySQL server has gone away” when innodb_kill_idle_transaction set to low value and bulk insert/delete process takes too long time Fixed bug 1488685: pt-kill option –filter does not work Feature 1402051: pt-online-schema-change should reconnect to slaves Fixed bug 1491261: pt-online-schema-change, MySQL 5.6, and InnoDB optimizer stats can cause downtime Fixed bug 1494082: pt-stalk find -warn option is not portable Feature 1389041: Document that pt-table-checksum has high likelihood to skip a table when row count is around chunk-size * chunk-size-limit
2.2.17 has just been added. Thanks!
