GitHub's Merge Queue, now generally available, enhances software delivery workflows by automating the merging of pull requests into busy target branches, ensuring they are merged in the correct order and reducing continuous integration (CI) workloads and potential delivery blockers. This tool, which has been used by companies like Uber and Shopify for years, is beneficial for organizations with numerous contributors and high volumes of pull requests, preventing merge conflicts and build backlogs. Merge Queue operates by creating temporary branches to validate pull request changes and incorporates changes into a merge group with the latest base branch version and other queued pull requests. It requires specific configurations in pipeline settings and GitHub repository settings, such as branch limiting and webhook adjustments, to function effectively. While the tool promises increased efficiency, it currently faces limitations, such as incompatibility with branch protection and required checks in Buildkite, though improvements are being considered.
