Learn how to diagnose and fix Bazel action cache misses. This guide covers identifying non-deterministic toolchains, environment leakage, and binary discrepancies using execution logs.
Bazel utilizes a content-addressable storage (CAS) system to ensure that action outputs are retrieved based on a hash of their inputs. In a remote caching environment, achieving consistent cache hits across different CI runners and developer workstations is critical for build performance. There is a design uncertainty regarding how Bazel handles absolute pat
