<div id=":29j">For the Java client API, the RabbitMQ documentation says that<div>a single channel should not be used by more than one thread, but</div><div>it does not explicitly say anything about connections.</div>
<div><br></div></div></blockquote><div><br>AMQP assumes that one connection is typically used by more than one channel. So<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

<div>BTW - I'm assuming that each connection corresponds to a</div><div>socket, and so opening lots of them consumes a somewhat limited</div><div>system resource.</div></div></blockquote></div><br>Long story short, this is true. Each connection has a frame handler that opens a new socket.<br>
