Code reviews can be particularly challenging for distributed teams due to time zone differences, which often lead to delays and reduced productivity. Traditional workflows, like Gitflow, exacerbate this issue by limiting developers to one open pull request (PR) at a time, causing bottlenecks. The stacked PRs workflow offers a solution by allowing developers to create a series of smaller, logically separated PRs that build on one another. This approach enables parallel review and development processes, reducing wait times and enhancing productivity for teams spread across different locations. Stacking improves visibility of code changes, simplifies dependency management, and minimizes merge conflicts, as each segment of code is reviewed in isolation by domain experts. Tools like Graphite facilitate this workflow, offering features such as automated merging and rebase conflict resolution, which streamline the process and help maintain a stable main branch. Companies like Meta, Google, and Asana have successfully implemented stacked PR workflows, achieving significant time savings and improved code review experiences.
