MySQL To NoSQL

Reddit Drop memcacheDB for Cassandra

News of the switch comes after Digg announced it had moved from MySQL to NoSQL.

In a blog post, Reddit's David Ketralnis praises the “seamless” migration - which took only ten days - and the “palpable” load-impact on the Reddit servers. Also getting the thumbs-up from the Reddit team, are Cassandra's ability to add nodes as load and storage requires, and the ability to move non-cache type data.

Reddit's decision to go with Cassandra, is neatly summed up in the blog post: “in case you are wondering why we chose Cassandra: it is way faster, more scalable, and has a rich and active development community full of extremely smart and helpful people.”
