Support fetching CAS objects via the Bazel HTTP caching protocol (enables CDN-backed remote storage)
@juergbi is already working on this.
Since Sep 8, 2026.
Assessment
This issue has not been assessed yet.
Description
BuildStream relies on buildbox-casd for all CAS access. The gRPC REAPI CAS protocol is efficient for low-latency environments but is difficult to put behind a standard CDN
Upstream work to add client-side support for this protocol as a remote in buildbox-casd's proxy mode is tracked here:
