In order to reliably store Go test times in the Github Actions cache we need to reduce our cache thrashing by not using more than 10gb over all of our caches. This change reduces our cache usage significantly by sharing Go module cache between our Go CI workflows and our build workflows. We lose our per-builder cache which will result in a bit of performance hit, but we'll enable better automatic rebalancing of our CI workflows. Overall we should see a per branch reduction in cache sizes from ~17gb to ~850mb. Some preliminary investigation into this new strategy: Prior build workflow strategy on a cache miss: Download modules: ~20s Build Vault: ~40s Upload cache: ~30s Total: ~1m30s Prior build workflow strategy on a cache hit: Download and decompress modules and build cache: ~12s Build Vault: ~15s Total: ~28s New build workflow strategy on a cache miss: Download modules: ~20 Build Vault: ~40s Upload cache: ~6s Total: ~1m6s New build workflow strategy on a cache hit: Download and decompress modules: ~3s Build Vault: ~40s Total: ~43s Expected time if we used no Go caching: Download modules: ~20 Build Vault: ~40s Total: ~1m Signed-off-by: Ryan Cragun <me@ryan.ec> Co-authored-by: Ryan Cragun <me@ryan.ec> |
