So the C client is different from the Java client implementation, which says that multiple<br>threads can share a connection, but not a channel:<br><br><div style="margin-left: 40px;"><a href="http://www.rabbitmq.com/releases/rabbitmq-java-client/v1.6.0/rabbitmq-java-client-javadoc-1.6.0/com/rabbitmq/client/Channel.html">http://www.rabbitmq.com/releases/rabbitmq-java-client/v1.6.0/rabbitmq-java-client-javadoc-1.6.0/com/rabbitmq/client/Channel.html</a><br>
<br>While a Channel can be used by multiple threads, it's important to
ensure
that only one thread executes a command at once. Concurrent execution
of
commands will likely cause an UnexpectedFrameError to be thrown.
<br clear="all"></div><br>Is my understanding correct?<br><br>If I have a multi-threaded Java client that needs many channels, then it is ok (and more efficient)<br>to have one connection and construct many channels from it?<br>

</div>I'm sorry to say that multithreaded use of librabbitmq will not work<br>
without quite a bit of effort. It is designed for event-based systems,<br>
not multi-threaded systems. Its internal architecture is quite different<br>
from our other client libraries, where sharing connections between<br>
threads is just fine.<br>
<br>
With that said, however, you *can* use librabbitmq with a connection per<br>
thread; just don't try to share a connection or its channels between<br>
threads at the moment.<br>
<br>
