Release candidate v1.1.8-rc adds major features including resumable migrations, revertible migrations, and GTID support. We invite the community to test these features and submit feedback or bug reports in an issue. After a period of further internal testing we will release GA v.1.18.

Thanks to all the contributors!

Changes

  • GTID support for binlog streaming by @timvaillancourt and @meiji163 in #1584
    • Use the --gtid flag to use GTID sets for binlog streaming instead of file-based coordinates (the default). This option requires gtid_mode=ON and enforce_gtid_consistency=ON.
  • Resume migration from checkpoint by @meiji163 in #1595
    • Use --checkpoint flag to write periodic checkpoints that can be used to resume an interrupted migration. As long as the relevant binlogs are still available, a migration can be resumed from the last checkpoint by invoking gh-ost again with --resume. It is recommended to use in combination with --gtid, which allows resuming from a different replica.
    • Please read resume.md before using. Also see #1595 (comment) for more details.
  • Revertible migrations by @meiji163 in #1607
    • Some migrations can be reverted after they complete by invoking gh-ost with the --revert flag and the --old-table flag, which specifies name of the "old" table from the original migration e.g. _<table-name>_del. The original migration must be invoked with --checkpoint and the relevant binlogs have to still exist on the inspected replica.
    • ⚠️ Migrations are only revertible under certain conditions. Please read revert.md before using. Also see #1607 (comment) for more details.
  • Add postpone-cut-over-flag-file interactive command by @yktakaha4 in #1561
    • The cutover flag file can be set via interactive command postpone-cut-over-flag-file=<path-to-cutover-flag>
  • PanicOnWarnings option to detect SQL warnings and fail the copy process by @grodowski in #1500
    • --panic-on-warnings will panic the gh-ost process if there are any SQL warnings during the copy phase
  • Add MySQL 8.4 Support by @chen-anders in #1494
  • Add triggers support by @yakirgb in #1503
    • Use --include-triggers to make gh-ost create the same triggers on the ghost at cutover time.
  • Remove restriction on password length and bump go-mysql to 1.11.0 by @joshvarner in #1525
  • Update status format in docs by @coding-chimp in #1512

  • Fix: Conversion bug when string data comes from binlog by @mattbooks in #1571
  • Fix: Ensure metadata lock is held by rename session by @abaowhy in #1536
  • Fix: Prevent exponential backoff from overflowing. by @burnison in #1491
  • Fix: TLS verify error when gh-ost discovers the replication master by @petervandoros in #1487
  • Fix: Output for binary keys in -verbose mode. by @burnison in #1559
  • Fix: Lexographical comparison of binlog filenames by @grodowski in #1604
  • Fix: Logic to include originalUniqueKey in sharedUniqueKeys by @htmsousa in #1453
  • Fix: Align max --dml-batch-size with the implementation by @yktakaha4 in #1575
  • Testing: sysbench localtest by @meiji163 in #1590
  • Testing: toxiproxy localtest by @meiji163 in #1591
  • Testing: copier test, upgrade testcontainers by @meiji163 in #1567
  • Testing: Use docker for CI replica tests, deprecate dbdeployer by @meiji163 in #1529
