[Rhm-users] how many queues can I have?

[Andrew M]

Well let's say I have various producers sending stock orders before the open
of trading.  When the market opens those orders are filled or cancelled and
execution reports come back. I want to make sure those executions get to the
app who produced the order.  Before the open I may have several hundred
thousand orders pending.  Is there a better way to go where I don't use an
individual temp queue for each order's reply?

Don't think you will get good memory use / lookup if you create that many
tmp reply queues at once. however if the tmp queue
for reply is short lived that is most likely ok. make them exclusive and
auto delete.

How many temp queues do you expect to have at once? This is the the factor
in using this pattern or not.

would I have 1,000,000 reply queues so that the execution or reject message
from the exchange would flow back to the originator of the order?  Or am I
off base on how that'd be implemented?

Thanks,

Andrew
