Description

We're using sccache v0.7.6, we have a lot of builds running in parallel and each run invokes sccache which in turn tries to do a sccache RW check by reading and writing .sccache_check dummy file. While this is fine for reading but for writing we violate the quota on GCS which allows write on the same object once per second.

Is there a way to bypass this check? We can perhaps create an env var to support this use case?

Contributor guide

Research direction
Propose adding an environment variable (e.g., SCCACHE BYPASS CHECK) to skip the .sccache check write operation for GCS to avoid rate limiting.
