Constant Summary collapse

VNODES =

VNODES is the number of queues in rabbit that are available for subscribing. The name comes from riak, where the data ring (160bits) is chunked into many vnodes; vnodes outnumber physical nodes, so one node hosts several vnodes. That is the same design we use here.

See the notes on topic queue benchmarking before adjusting this value.
