Can I sync two bazel-remote-cache's using rsync

I have a build pipeline that builds and tests changes before they are merged to the main line. Once that happens, it would be great if the Bazel actions from that build are available to developers. Unfortunately, the build pipeline runs in the cloud and uses an in-cloud cache, but the developers use an on-premises cache.

I am using https://github.com/buchgr/bazel-remote

Does anyone know if I can just rsync the artifacts from the data directory of the cloud cache to the developers' cache in order to give them access to the pre-built artifacts? Normally, I would just try it out, but I'm concerned about subtle issues that might poison the cache or negatively effect the hit rate, so I'm hoping to hear from someone who understands the code before I go digging.

You can rsync the cache directory contents and use them from another location, but this won't work with a running bazel-remote- the items will be ignored until bazel-remote is restarted.

Another option would be to use the http_proxy configuration file setting to automatically put/get cache items to/from another bazel-remote instance. An example configuration file was recently added to README.md in the bazel-remote git repository.
