The README explains that the name began as `gh-osc`, for GitHub Online Schema Change, before becoming `gh-ost`, and credits GitHub's database infrastructure team as designers, authors, reviewers, and testers. The project came out of GitHub's operational experience with MySQL schema changes at production scale. Its design follows the ghost-table migration pattern used by earlier online schema-change tools, but replaces trigger-based change capture with MySQL binary-log streaming so the tool can pause, throttle, audit, and control cut-over more explicitly. ### 采用历史 gh-ost became significant beyond GitHub because it offered a production-tested alternative to pt-online-schema-change and Facebook's online schema-change lineage. Its documentation includes cloud and managed-database notes, test-on-replica guidance, interactive commands, hooks, and operational limits, making it attractive to teams that needed safer MySQL DDL changes. ### 使用方式 Practitioners run gh-ost in noop, replica test, replica-assisted master migration, direct master migration, or replica-only modes. Common practice is to test on replicas, run a noop check, execute the migration, watch throttling and lag controls, and postpone cut-over until an operator chooses the swap window. ### 为什么软件包爱好者会关心 For package-manager users, gh-ost matters because it turns a sophisticated database migration workflow into a single Go binary available through releases and packages. That makes online schema migration scriptable in deployment pipelines while keeping the operational controls visible at the command line. ### 时间线 - 2016: The GitHub repository was created. - 2016: v0.7 was published as a pre-production release. - 2016: GitHub published an engineering article describing gh-ost as its online migration tool for MySQL. - 2026: The release feed showed the v1.1 series. ### Related projects - The README explicitly relates gh-ost to Facebook online schema change and Percona's pt-online-schema-change, while highlighting its triggerless binlog-based design. ### 来源 - - - - - - - ## 安全说明 broad file, network, media, or database tool signal. - **Geiger 风险:** blue / 中 - broad file, network, media, or database tool signal ## 其他软件包管理器记录 - Nix - gh-ost: normalized package name match | nixpkgs package indexes: pkgs/by-name/gh/gh-ost/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
