QPush Demo

This is a very rough and ready demo of using IronMQ push queues with the uecode/qpush-bundle.
Installation
- run composer install to install symfony and the other dependencies
- create an account on http://www.iron.io/ (it's free for 10 million API calls per month)
- create an IronMQ project
- copy the Token and Project ID and put them into app/config/parameters.yml
e.g.
ironmq_token: <token here>
ironmq_project_id: <project id here>
- install ngrok from https://ngrok.com/ - we'll use this to tunnel from the internet to your machine
- start the symfony built in webserver in a new terminal window -
app/console server:run - start ngrok in a new terminal window -
ngrok 8000 - paste the nrgok url into app/config/parameters.yml
eg.
ironmq_endpoint1_url: http://<something>.ngrok.com
- all being well, you can run
app/console app:demo1. This will post 10 messages to IronMQ.
If you examine app/logs/dev.log (try tail -f dev.log | grep --line-buffered app.INFO) you'll see the messages being
posted, and then the inbound messages being processed by src/Inviqa/Bundle/QPushDemoBundle/Service/Queue1Service.php.
The implementation simulates random failures, and you should see that IronMQ retries. Ultimately it will give up.
IronMQ by default gives a job 60 seconds to complete. After that it'll be put back on the queue.
IronMQ will send one job at a time to the pool or endpoints.
TODO:
- experiment with listing the same endpoint multiple times (and changing the IronMQ push configuration to 'unicast')
- experiment with creating multiple queues
- read about the other configuration options at http://qpush-bundle.readthedocs.org/en/latest/index.html
