Storage technologies at HipChat - CouchDB, ElasticSearch, Redis, RDS

As per the list below, HipChat’s storage solution is based on a couple of different solutions:

  • Hosting: AWS EC2 East with 75 Instance currently all Ubuntu 12.04 LTS
  • Database: CouchDB currently for Chat History, transitioning to ElasticSearch. MySQL-RDS for everything else
  • Caching: Redis
  • Search: ElasticSearch
  1. This post made me wonder what led HipChat team to use CouchDB in the first place. I’m tempted to say that it was the master-master replication and the early integration with Lucene.
  2. This is only the 2nd time in quite a while I’m reading an article mentioning CouchDB — after the February “no-releases-but-we’re-still-merging-BigCouch” report for ASF. And according to the story, CouchDB is on the way out.
