[openamq-dev] Basic questions about OpenAMQ

[Terry Jones]

Hi all.

I'm completely new to OpenAMQ. There are a few simple things I'm wondering
about, and would really appreciate any responses.

- Firstly, this mailing list is rather quiet.  Does that mean there's not
  much work going on on OpenAMQ, that the developers are all physically
  together and don't use the mailing list much for everyday discussion, or
  something else?  Note: I have no idea. I'm not trying to get myself
  flamed :-)  Just wondering.

- Is queue creation a cheap operation, in terms of speed and/or space? Is
  OpenAMQ going to have a problem creating 1000 queues? What about 100K?  I
  know this depends partly on the underlying machine, so for the sake of
  argument assume I have a standard Linux box with 4GB of RAM.

- Can a client find out how many other clients are listening on a queue?

- Can a client tell if a queue exists (other than by attempting to consume
  from it)?

- We wrote some sample Python code to talk to a qpid server and then
  adapted it to OpenAMQ. The qpid code used channels. The code continued to
  work when talking to OpenAMQ. Given that OpenAMQ doesn't support
  channels, does that mean that OpenAMQ simply ignores the channel? This
  seems like an obvious "yes", but I wanted to ask.

Thanks for any help. Apologies if the questions are stupid or poorly worded.
