I think it’s just a bit badly worded. You don’t normally throw them away, you leave them in the queue for later. For instance if you have a process that gets requests and writes stuff to DB, while processing a request you can send a message to the DB, then use a selective receive to match on the response from the DB while ignoring all other messages (you’ll deal with them later i.e. when you fetch the next request to process).

So "discard" means to post messages to own message queue? If so it seems like an awkward pattern that essentially implements a priority queue.

  No, messages that don’t match are not dequeued in the first place. I don’t know why the other poster used the word discard.
