I’m creating a sort of background job queue system with MongoDB as the data store. How can I “listen” for inserts to a MongoDB collection before spawning workers to process the job?
Do I need to poll every few seconds to see if there are any changes from last time, or is there a way my script can wait for inserts to occur?
This is a PHP project that I am working on, but feel free to answer in Ruby or language agnostic.
