sccache-dist also used for caching requests or only compilation?

[bhouse-nexthop]

I'm looking at setting up an sccache-dist build infrastructure and was curious if build caching also happens through sccache-dist or if I need to explicitly set up my S3 cache on every single build client? Obviously having those credentials only in a central place would be optimal but it wasn't clear from the docs if that was the case.

I also see the docs state that a local sccache server is spawned client side, is that true when configured for distributed builds?

Distributed compiles don't talk to the cache. The client checks the cache and sends for distributed compilation in case of a cache miss, gets the compiled object and pushes it to the cache.
