Concurrency with Redis Semaphore

It does! Thank you very much!

Hi @LeorGreenberger ,

When multiple threads in the same process try to acquire any of the distributed semaphore implementations (including Redis), it behaves just as if two threads from different processes tried to acquire.

You are correct in thinking that many threads in the same process can share the same underlying connection to Redis and that holding on to the semaphore between acquisition and release does not block others from using that connection.

Because of the way Redis locks work, if acquisition fails and there is no timeout (or the timeout isn't met), it will enter a wait-retry loop.

Does that answer your question?
