Presque - what is it ? presque is a persistent job queue that uses Redis for storage and Tatsumaki for the interface between workers and Redis. presque implements a REST interface for communications, and jobs are JSON data structures. Workers can be written in any language as long as they implement the REST interface.

Plack / Tatsumaki asynchronous fast ideal for ReST applications middlewares!

Redis "like memcache with persistence" fast multiple data types AnyEvent::Redis for asynchronous access (and it's fast!)

Presque - why ? you need to send jobs you don't want to be limited to Perl only (hello, javascript) simple to use (ReST API) JSON is easy to use

Presque - how (jobs) insert a job curl -X POST -H 'Content-Type: application/json' http://localhost:5000/q/foo -d '{"foo":"bar"}' fetch a job curl http://localhost:5000/q/foo {"foo":"bar"}

Presque - control You can change the status of a queue: by default, a queue is "open". You can change to "close", jobs will still be inserted, but not fetched. curl -X POST http://localhost:5000/control/foo -d '{"status":"stop"}' {"response":"updated","queue":"foo"} curl http://localhost:5000/q/foo {"error":"queue is closed"} curl -X POST http://localhost:5000/control/foo -d '{"status":"start"}' {"response":"updated","queue":"foo"} curl http://localhost:5000/q/foo {"foo":"bar"}%

Presque - monitoring get information about your queue: curl http://localhost:5000/j/foo {"queue_name":"foo","job_count":"1","job_processed":"3","job_failed":0}

Presque - features simple interface (yes, it's a feature) possibility to interact in batch mode with queues (massive insert, massive get) delayed jobs (run a job after a certain time) statistics about queues AND workers

Presque - soon real admin interface PUB/SUB WebSocket ?
