Slack (Sloth) + Cassandra : Experiment with Slack API and Apache Cassandra
Written in Java and Node.js
https://slack.com/ is a great chat application but it's free version has limitation. Free version keep 10,000 most recent message so we cannot look up for very old message.
Slothsandra solve that limitation. It has slack bot that will store all public chat message into Apache cassandra. It also provide UI for lookup all message from Apache cassadra.
