Scaling Real-Time Comments @ HuffPost Live with RabbitMQ

Last week, one of the engineering leaders from Huffingtonpost.com presented at the Erlang Factory, a 2-day conference held in San Francisco with 50+ speakers across 8 tracks (not the cassette kind). Among the presenters was, Adam Denenberg, VP of Engineering at the Huffington Post and HuffPost Live. Besides leading the engineering teams for Huffingtonpost.com and HuffPost Live, Adam is also responsible for community products and advertising platforms.

  • How they integrated RabbitMQ routing to power the subscription architecture
  • How they managed subscriptions for real time channels
  • Their plans to extend the framework into an open source solution
  • Where they want other mechanisms for publishing comments outside of RabbitMQ Continue reading
