Hi Roedy,

thanks for your reply. I see what you mean. You would mostly play with
control valves that are outside the software like adding servers or
adding RAM.

Let's say there are 10 consumers and everyone takes messages from a
queue exclusively assigned to itself. Consequently, there are 10
queues in total. Now, each queue is filled with 100 messages each. I
would expect these 1000 messages in total to be processed faster this
way than, say, 1000 messages sitting in a single queue served by a
single consumer. Naively speaking, those 10 consumers should eat up
those 1000 messages 10 times faster. But this is pure mind gambling.
No clue how things would turn out in reality. Maybe the increased
network traffic of 10 consumers polling a queue instead of a single
one would decrease performance...

Do you think it would be useful to make the "message bus" pluggable in
the sense that some SPI is provided so that anyone can increase the
number of queues if considered appropriate? I wonder whether that kind
of pluggable message bus system already exists. Guess it does since
there must be a need for something like this.

Regards, Oliver
