<div><br></div><div>- REST API to push ( POST ) data into a queue</div><div>- The Queue has a Consumer that's always running and Produces to en Exchange</div><div>- The Exchange routes to several other Queues ( like 20+ )</div>
<div>- Each of the ( 20+ ) Queues does a specific task ( The Consumers always runs as well )</div><div>- Cron job runs to check if all the ( 20+ ) Tasks are completed and Produces to yet another Queue</div><div><br></div>
<div>I'm not sure I like the Consumers running all the time as each Consumer utilizes around 300MB of Ram ( I think it's MBs, it's not in front of me at the moment ) and I'm looking for another implementation.</div>

This is a resource intense process as is and I think by adding the RPC calls it will just bog down the server and then become unresponsive ( Please correct me if I'm wrong ).</div>

I'm looking to either get rid of the CRON, Implement a new Pattern and Not have the Consumers run all the time.</div>
<div><br></div><div>The process currently also only supports a single instance of each consumer. It can have multiple consumers but how we have implemented it we only wanted one at the time.</div><div><br></div><div>This is implemented in PHP, Symfony2 Framework using the RabbitMQBundle</div>
