On the record
- Architecture
- Workers can perform execution and CAS shard roles, and either role can be disabled in configuration.buildfarm.github.io · read 5 Oct 2026
- Backplane dependency
- Buildfarm requires a backplane for information shared between cluster members, and its quick start uses Redis for that role.buildfarm.github.io · read 5 Oct 2026

- Buildfarm documents in-memory storage, an external CAS proxy, an HTTP/1 proxy, and persistent worker disk storage as CAS implementations.buildfarm.github.io · read 5 Oct 2026
- Deployment
- The project documents running Buildfarm server and worker processes, using containers for a minimal cluster, and installing an OCI bundled Helm chart.buildfarm.github.io · read 5 Oct 2026
- Deployment scale
- The quick start says deployments can spread servers and workers across machines and describes use by hundreds or thousands of developers or CI processes.buildfarm.github.io · read 5 Oct 2026
- Execution controls
- Execution policies can modify or control worker actions, including wrapper policies such as running actions through the Linux sandbox or as the nobody user.buildfarm.github.io · read 5 Oct 2026
- Experimental limitation
