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 new installations or for testing. This option will be removed in the Mitaka release.
[oslo_messaging_rabbit] kombu_reconnect_timeout = 60 (IntOpt) How long to wait before considering a reconnect attempt to have failed. This value should not be longer than rpc_response_timeout.
