2020-12-17 05:32:24 Roy Zuo description Current rpc model uses direct exchanges for rpc.call replies, and this results in too many direct "reply_<uuid>" exchanges and this makes rabbitmq maintenance as well as message tracing difficult. In the attached rabbitmq report, there are 25136 exchanges in total, of which 25071 are "reply_" exchanges. For reference there are only 30481 queues. It would be easier if topic consumer directly publish reply to the control exchange with routing key simply be "reply.<uuid>" or even with more keys in there. Also, if topic publisher only subscribe to "reply.*" from a handful of control exchanges instead of every "reply_<uuid>" exchanges, there will be much less bindings for rabbitmq. Not only easier to maintain, but less chance for binding churns when service goes down and back up again. +---------+ +----------+ key: topic +-------+ +--------+ | topic |--------------------------->| control |<===========| | | | |----->| topic | | | +-------+ | | +-------+ | | |publisher|<----| | | | |=============>| exchange |<--------------------------|consumer| +---------+ +-------+ key: reply.* +----------+ +--------+ Current rpc model uses direct exchanges for rpc.call replies, and this results in too many direct "reply_<uuid>" exchanges and this makes rabbitmq maintenance as well as message tracing difficult.
