With over 1,000,000 downloads, Percona Toolkit supports Percona Server for MySQL, MySQL®, MariaDB®, Percona Server for MongoDB and MongoDB.

Percona Toolkit, like all Percona software, is free and open source. You can download packages from the website or install from official repositories.

This release includes the following changes:

New Features:

  • PT-1571: Improved hostname recognition in pt-secure-collect
  • PT-1569: Disabled --alter-foreign-keys-method=drop_swap in pt-online-schema-change
  • PT-242: (pt-stalk) Include SHOW SLAVE STATUS on MySQL 5.7 (Thanks Marcelo Altmann)

Fixed bugs:

  • PT-1570: pt-archiver fails to detect columns with the word *GENERATED* as part of the comment
  • PT-1563: pt-show-grantsfails for MySQL 5.6 producing an error which reports that an unknown column account_locked has been detected.
  • PT-1551: pt-table-checksum fails on MySQL 8.0.11
  • PT-241: (pt-stalk) Slave queries don’t run on MySQL 5.7  because the FQDN was missing (Thanks Marcelo Altmann)

Breaking changes:

Starting with this version, the queries checksum in pt-query-digest will use the full MD5 field as a CHAR(32) field instead of storing just the least significant bytes of the checksum as a BIGINT field. The reason for this change is that storing only the least significant bytes as a BIGINT was producing inconsistent results in MySQL 8 compared to MySQL 5.6+.

pt-online-schema-change in MySQL 8:

Due to a bug in MySQL 8.0+, it is not possible to use the drop_swapmethod to rebuild constraints because renaming a table will result in losing the foreign keys. You must specify a different method explicitly.
