Diagnose remote-cache misses systematically.
A hit-rate percentage is the beginning of an investigation, not the answer. Diagnose misses at the action level and compare the exact inputs that determine each action key.
Understand the mechanism
Learn how Bazel caches action results and why equivalent-looking builds may compute different action keys.
Investigate a regression
Capture comparable execution evidence and isolate input, command, environment, tool, platform, namespace, or policy differences.
Monitor the result
Track equivalent workloads over time and investigate unexpected misses at the action level.
Investigate your own build data.
