gh-ost v1.1.11 includes MariaDB support, StatsD metrics, improved binlog processing, and several reliability and release/build improvements.

Thanks to all the contributors! 🙇‍♂️

What's Changed

New Features

• MariaDB and MariaDB GTID support (#1724, #1731) by @conf: Adds automatic server-flavor detection, MariaDB-specific replication behavior and privileges, and MariaDB GTID migrations. CI covers MariaDB 10.5, 10.6, 10.11, 11.4, and 11.8.
• StatsD/DogStatsD metrics (#1701) by @forge33: Adds opt-in telemetry for copy progress, applied DML, binlog backlog, replication and heartbeat lag, throttling, cut-over attempts and phases, query latency, sleep time, and Go runtime health. Global metric tags are supported.
• Pre-cutover table analysis (#1747) by @VandhanaSelvaprakash-at: Adds the --analyze-ghost-table-before-cutover flag, which runs ANALYZE TABLE before swapping tables to help prevent stale optimizer statistics. The feature is opt-in and aborts cut-over if analysis fails.

Bug Fixes and Improvements

• Data-race fixes (#1750) by @ericyan: Synchronizes concurrent migration state more consistently and enables Go's race detector in CI to catch regressions.
• More efficient binlog processing (#1699) by @coding-chimp: Skips decoding row payloads for tables unrelated to the migration, reducing CPU and allocation overhead on servers with busy binlogs.
• More portable release binaries (#1697) by @meiji163: Disables CGO by default for release builds, reducing runtime dependencies and platform compatibility problems.
• Multi-flavor replica-test harness (#1722) by @conf: Expands automated integration testing across MySQL, Percona Server, and MariaDB versions.
• Improved release packaging and workflow (#1729 and #1753) by @conf and @ericyan: Standardizes archive and package names and a GitHub workflow to build and attest the release artifacts.

Maintenance and Documentation

• Core dependency updates (#1715) by @ericyan: Upgrades go-mysql to v1.15.0.
• Test and security dependency updates (#1741) by @ericyan: Upgrades Testcontainers to v0.43 and x/crypto to v0.54.
• OpenTelemetry dependency updates (#1740) by @dependabot[bot]: Upgrades go.opentelemetry.io/otel/sdk from v1.21.0 to v1.43.0.
• Go toolchain update (#1742) by @ericyan: Upgrades the project to Go 1.25.12.
• Test build cleanup (#1739) by @davidham: Restricts Testcontainers helpers to test builds.
• GitHub Actions updates (#1576, #1589, #1598) by @dependabot[bot]: Upgrades actions/checkout, github/codeql-action, and actions/upload-artifact.
• Command-line flag documentation (#1706) by @grodowski: Documents previously missing command-line flags.
• Throttle replica documentation (#1745) by @soepic1: Clarifies replica-selection requirements for --throttle-control-replicas.
• Documentation spelling corrections (#1749) by @vladdoster: Corrects spelling errors in the documentation.

GA release v1.1.9 is a small release with some bug fixes. We are aiming to make smaller releases more regularly.
Thanks to all the contributors!

What's Changed

• Add retry logic for instant DDL on lock wait timeout by @yosefbs in #1651
• Retry attempt InstantDDL up to --default-retries by @meiji163 in #1667
  • When --attempt-instant-ddl is enabled, it will retry on lock wait timeout up to --default-retries times. Retries are necessary in high-concurrency environments with metadata lock contention
• Fix handling of warnings on DML batches by @ggilder in #1643
  • Previously --panic-on-warnings only detected SQL warnings for the last DML in each batch. Now it is guaranteed to detect all warnings.
• Update golangci-lint to v2.11 by @meiji163 in #1657
  • Error messages have been lower-cased. Please be aware if you are parsing error logs.
• Add GH_OST_INSTANT_DDL for gh-ost-on-success hook by @meiji163 in #1658
  • GH_OST_INSTANT_DDL environment variable is available on the success hook script to indicate whether InstantDDL succeeded or not.

GA release v1.1.8 includes new features such as GTID support, MySQL 8.4 support, and migration checkpoints, as well as several critical bug fixes. Please submit any questions or bug reports in an issue.

Big thanks to all the contributors!

Changes

• Add MySQL 8.4 Support by @chen-anders in #1494
• 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.
• PanicOnWarnings option to detect SQL warnings and fail the copy process by @grodowski and @ggilder in #1500 and #1633
  • --panic-on-warnings will panic the gh-ost process if there are any unexpected warnings while copying rows or applying row changes.
  • This prevents data loss for migrations that would violate a unique key constraint.
• Add --skip-metadata-lock-check by @meiji163 in #1616
  • Use --skip-metadata-lock-check if you are running with performance_schema disabled. However, enabling performance_schema is recommended due to #1536.
• (Experimental) 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>.
• Add a gh-ost-on-batch-copy-retry hook which is invoked when a batch copy fails by @grodwoski in #1507
• Add trigger support by @yakirgb in #1503 and #1626
  • Use --include-triggers to make gh-ost create the same triggers on the ghost table at cutover time.
• Fix: Avoid logging MySQL connection configs by @meiji163 in #1501
• Fix: Add support for unique text column, they are mapped to uint8[] by @markmarkmarkthebest in #1583
• Fix: Ensure metadata lock is held by rename session by @abaowhy in #1536
• Fix: Panic if InitiateHeartbeat exhausts retries to avoid looping infinitely by @grodowski in #1594
• Fix: Conversion bug when string data comes from binlog by @mattbooks in #1571
• Fix: Converting binary to varbinary strips trailing 0's @jorendorff in #1628
• Fix: Prevent exponential backoff from overflowing. by @burnison in #1491

Changes since 1.1.4: v1.1.4...v1.1.5

gh-ost v1.1.5 is based on v1.1.4, plus commits cherry-picked from master branch.

Notable:

• Cancel any row count queries before attempting to cut over, #846, thanks @ajm188
• Add context/timeout to HTTP throttle check, #1131, thanks @timvaillancourt
  • Throttler will now throttle migration on HTTP timeouts to throttler source. This may cause a change in behaviour in rare cases (more throttling)
  • New command line flags:
    1. --throttle-http-interval-millis - Number of milliseconds to wait between HTTP throttle checks (default 100)
    2. --throttle-http-timeout-millis - Number of milliseconds to use as an HTTP throttle check timeout (default 1000)
  • HTTP throttler calls now use gh-ost/VERSION-HERE as a User-Agent header
• Use switch statements for readability, simplify .NewGoMySQLReader(), #1135, thanks @timvaillancourt
• Ensure mysql rows responses are closed, #1132, thanks @timvaillancourt
• compound pk tests, #387, thanks @shlomi-noach
• Fix integer divide by zero panic in migrator, #1140, thanks @timvaillancourt for the PR and @ethankhall for reporting
• fix: lost data in mysql two-phase commit, #1141, thanks @shaohk
• Add golangci-lint CI action, fix gosimple, govet + unused lint errors, #1127, thanks @timvaillancourt
• Check RowsAffected when applying DML events to get more accurate statistics, #844, thanks @ajm188

Deprecation Notice:

• --replication-lag-query command line flag will be deprecated in gh-ost release 1.1.7

This release is not based on the master branch as it contains a known issue that is currently being investigated - please note that the master branch of gh-ost is not considered stable; only releases are considered production-ready.

Thank you to all contributors!

Updated 20th July 2022: RPM and deb packages have been updated to correctly include x86-64 binaries instead of arm64 binaries (thanks @Cartman75 for the issue report!)
