protobuf/grpc uses pre-build binaries

[nstng]

A fresh (cache-less) bazel build takes a long time to compile protobuf/grpc libraries. See rules-proto-grpc/rules_proto_grpc#165 for a workaround.

• try the workaround in Slow compiling every time? rules-proto-grpc/rules_proto_grpc#165 (comment) and evaluate if this improves the current state
• also needs to work with arm
• needs to work with remote caches
• if the workaround improves the current state then implement it and ...
  • track this sufficiently with a TODOGH12345 and an open issue - this should be removed if it is solved upstream

[nstng]

team unsure for now if this workaround is a good idea - will be kept in backlog for now

The speed of fresh bazel build's is also a subject of #13362 - having more remote cache hits might amend this problem.

I tried the workarounds in the mentioned issue in the description - but could not make it work. Maybe it can be tried again with a longer timebox.

Perhaps worth trying out for Magma?
