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

next stage, the team will directly connect users to the Java server
and eliminate Ruby-on-Rails from the search stack.
