There was a problem hiding this comment.
It should use blob.open instead of caching. Caching has the side effect that it may fill up the disk space, so it's not a good idea to transparently apply caching when reading. Instead, users should explicit call for caching if needed, by using get_local_path.
We apply this strategy to some internal storage backends as well.

I ended up using a fork and de-prioritizing making this PR, but we have been using this code for months and I figured I'd finish this PR to share it with everyone else :) |

Summary
Adds a GCS file handler, similar to one in S3.
Test plan
Wrote a test for it, and ran it on my setup. I also used this in a multi-threaded environment with torch DDP and indeed it works :)
