I did not check the code, but from memory it's simply that ring-buffer-
max-size enables a special queue2 mode where queue2 maintains a ring
buffer in RAM an lets downstream operate in pull mode while upstream
operates in push mode. With ring-buffer-max-size not set (and also no
backing temp file set), queue2 will operate like a normal queue.
You would typically not set both sizes. What you describe sounds like a
bug, I think it should probably ignore max-size-bytes if it operates in
ring buffer mode, which I don't know if it does in your case.
