Pub/sub example for nodejs using mongodb

Uses capped collection, tailable cursors and streams.

What's here?

  • init.js recreates collection capped collection 'queue' on mongodb.
  • writer.js spams queue with new messages
  • worker.js processes all messages saved to queue,
  • onceWorker.js processes only unprocessed messages, so you can spawn several of them and each of your messages will be processed by only one worker.

Steps
