This is partially true. What matters is publisher and consumer locality.
For maximum throughput you want to avoid intra-cluster traffic.
In an HA setup, your clients need to reconnect to another node, so likely
you won’t get in a situation when most clients are connected to a single node.
If that’s not good enough, you can use HTTP API to find what node hosts master
for the queue in question and connect there.
