Remote Cache CDC: Reusing Bytes
Summary
A technical blog post from BuildBuddy detailing Content-Defined Chunking (CDC) applied to Bazel remote caching. It explains how CDC enables chunk-level reuse of large outputs to reduce data transfer, outlines the architectural changes, and shares real-world gains from Bazel integration, including notable reductions in uploaded data and cache size. The piece also provides practical guidance on enabling CDC in Bazel builds and references related Bazel and BuildBuddy work.
