Vorpal Bunny is an experimental rabbitmq-jsonrpc-channel PHP driver designed to allow expedited single call HTTP delivery for Basic.Deliver calls to RabbitMQ.<div><br></div><div><meta charset="utf-8"><font class="Apple-style-span" face="helvetica, arial, freesans, clean, sans-serif"><span class="Apple-style-span" style="line-height: 20px;">The goal is to be a light-weight tool for higher throughput with smaller protocol overhead for single-call of Basic.Push per application execution. </span></font></div>
<div><font class="Apple-style-span" face="helvetica, arial, freesans, clean, sans-serif"><span class="Apple-style-span" style="line-height: 20px;"><br></span></font></div><div><font class="Apple-style-span" face="helvetica, arial, freesans, clean, sans-serif"><span class="Apple-style-span" style="line-height: 20px;">Our use case is focused on PHP web applications that span hundreds of servers with hundreds of backends each. With the existing AMQP drivers for PHP, applications can not currently maintain consistent connections and publish across application executions, instead they connect, publish and disconnect. Vorpal Bunny is intended to reduce the overhead on the RabbitMQ server and the PHP application by using the jsonrpc-channel plugin, which maintains its own channels per session inside RabbitMQ's running instance, eliminating most of the AMQP protocol overhead for one off message delivery.</span></font></div>
