Why use the C++ broker versus the Java broker?
Hi. I'm new to Qpid (and AMQP in general). I'm having a bit of trouble
determining which broker to use. The compatibility page[1] says:
There are two brokers:
C++ with support for AMQP 0-10
Java with support for AMQP 0-8, 0-9, and 0-10.
The C++ broker supports only a subset of what the Java broker does, so
is there any reason (other than the never-ending performance
comparisons between Java and native languages) to use the C++ broker?
Is the Java broker being replaced by the C++ broker? Is the C++ broker
intended mainly for platforms without a reliable Java run-time? The
permissions structure seems to differ between the two brokers, with
the C++ broker relying on a newer ACL system, but I haven't used it
yet, so I'm relying on the (somewhat sparse) documentation. I've tried
to search the list archives for answers to these questions but the
only info I found referred to version 0.6, so I'm not sure that the
info is still current.
Will someone explain this to me? Is this something that should be in
the FAQ or am I just missing something obvious?

Thanks for the explanation. I think I'll stick with the Java broker
for compatibility.

I think its really a question of personal preference at this point in
time (some people feel more comfortable with one broker, others with
another). The java broker can run pretty much anywhere there is a jvm,
the c++ broker is more restricted (at least at present). The c++ broker
has support for some 'native' features (e.g. RDMA). As you point out the
java broker also speaks all versions of AMQP to date (the only broker
known to do so!).
Ultimately I would hope the choice would not be too significant and
switching between the two as needed would not cause much disruption to
an application, at least at the semantic level. We are moving towards a
more uniform feature set and a more uniform management schema, but are
still some way of that.
Thats just my 2cents...

Hi Drew,
I my experience as a beginner to qpid I spent allot of time with the Java broker versions 6 and 7. I was trying to get some publish and subscribe applications working with SSL. With help from this board I came to the conclusion that it was beyond my skills or not possible using the Java broker. So I used the C++ broker and got it working quickly using my java clients.
So, I think the C++ is better in this side of things and the documentation also seems to be a bit more complete for the C++ version.
Cheers,
Tom
