Does ccache fetch compiled code from a central server using checksums?

buildcache, the program the post is about can use a remote server for storing the cache.

And a local cache (kind of level 1 and level 2 caches)

sccache can, but most of us don't have access to an sccache instance: https://github.com/mozilla/sccache

sccache is pretty easy to set up and you can back it with S3, memcache, redis, etc.

Same with BuildCache, except you also get a fast local cache so you effectively have an L1 and an L2 cache.

In fact, since you also have super fast "direct mode" caching that bypasses the preprocessor (like ccache but unlike sccache), BuildCache really has three logical levels of cache: direct, preprocessor and remote (S3, redis, ...).

We use sccache on prem with MinIO.
