What is Maximum number of Queue bind to single exchange?

[Hitendrasinh Mahida]

Hi Users,

I am looking forward to bind more than 10k queue to single (Topic)exchange.

Will there be any performance issue (my server runs on best H/W config.) because of this ? What is max limit to bind number of queue to single exchange ?

Thanks for helps.

Regards.

The topic exchange uses a trie internally, so it should scale fairly well w.r.t.
the number of queues bound:

There is no limit that RabbitMQ enforces but there is a natural limit to how many
queues you can have and the throughput of a single exchange in general.

As always, run some benchmarks in your own environment and see. Feel free to post
them on this list , too.

Hi MK,

Thanks for your reply, I will do that test from my side. Also is there any known limit for number of exchange can be created on single node?

Exchanges are just routing tables so they are much cheaper than queues.
I don't think we've ever seen anyone max out a single node on the # of exchanges.
