Twitter Switch from Ruby-on-Rails to Java

Twitter have replaced their Ruby-on-Rails front-end with a Java server, and have reported a 3x drop in search latencies as a result. "Over time, we had also accrued significant technical debt in our Ruby code base, making it hard to add features and improve the reliability of our search engine," reads the announcement. The new Java server is a Thrift and HTTP service built on Netty. Twitter are currently using the Ruby-on-Rails front-end servers as proxies for routing thrift requests to the new Java cluster. In the next stage, the team will directly connect users to the Java server and eliminate Ruby-on-Rails from the search stack.
