send_single_reply = False |
(BoolOpt) Send a single AMQP reply to call message.

We are going to remove it in the N release, but we must keep backward compatible at the same time. This option provides such compatibility - it defaults to False in Liberty and can be turned on for early adopters with a new installations or for testing. Please note, that this option will be removed in the Mitaka release. |
