Technical Aspects

BuildFetch Cache now implements the Ccache Remote Storage protocol and storage schema.

BuildFetch Cache acts as a Ccache HTTP remote storage backend in both Cloud and On-Premise deployments, with distributed In-memory → NVMe → SSD storage.

As with any Ccache-backed setup, cache reuse depends on matching compiler identity, flags, source inputs, and the relevant build environment details.

When we add support for new protocol & toolchain, this includes extensive unit and integration tests, as well as end-to-end tests.

For Ccache we have end-to-end test suite that:

  1. Spins up BuildFetch Cache in Kubernetes cluster
  2. Creates Ccache project
  3. Sets up source code, stable version of Ccache and clang
  4. Runs Ccache build twice
  5. Verifies that first Ccache build uploaded expected cache entries to BuildFetch Cache
  6. Verifies that the second Ccache run got 100% cache hit that we verify both in our backend and in Ccache output.

This way any change to Ccache related code will re-run these tests in BuildFetch Monorepo ensuring we did not break Ccache compatibility.

See Configure Ccache Remote Storage setup docs for more details.

Product Vision

BuildFetch needs to carve out a unique position in the market by covering build cache for the entire tech stack of real startups and enterprises:

  • Backend: Go, Rust, C++, JVM, TypeScript
  • ML & AI: C++, Rust, NVIDIA CUDA, AMD ROCm HIP
  • Frontend: TypeScript
  • Mobile & Desktop: Swift, Kotlin, Electron

All with a single subscription to BuildFetch Cache, whether Cloud or On-prem.

When a build in your company takes 30 minutes and the team is scrolling Twitter waiting, while your competitors ship with 3-minute builds and barely stock up on coffee — that’s a business problem, not just a developer problem.

BuildFetch Cache is on a fast track to become the single build cache solution for your entire tech stack across engineering departments with new cache protocols rolling out every ~1.5 weeks.

Kind regards, Tommy Zinnatullin. CEO & Founder of BuildFetch Inc.
