Is it safe to use it with concurrency? about cache HOT 4 OPEN

Same concern, while reading the code I saw it is not thread-safe. But need the confirmation from the dev team. At the moment I init the cache instance per request.

It looks to me as though the cache is safe to run in a concurrent system. Instead of relying directly on channels or mutex, it seems to use singleflight.Group. The Once() function in particular is a clever way of handling duplicate requests of the same key in parallel--I'm looking forward to trying this library since it's already got code I thought I'd have to write . . .

Has anyone found out whether this is concurrency safe yet?

Same situation. I would love to here a reply from the dev team.
