Bazel Persistent Workers - Cutting Build Times in Half

Learn how persistent workers can significantly reduce Bazel build times by amortizing startup costs and enabling cross-action caching through long-running processes. This 19-minute Linux Foundation talk by Susan Steinman and Lars Clausen explains implementation techniques, tuning strategies, and introduces multiplex workers while discussing the evolution of the worker protocol. Discover practical guidance on using, creating, and optimizing workers for your Bazel builds with references to comprehensive documentation on worker functionality, multiplex worker implementation, dynamic scheduling, and lock handling approaches.
