Parsoid/OPW tasks

Cassandra backend for distributed round-trip test server
Our distributed round-trip test setup thoroughly tests Parsoid by converting 160000 Wikipedia articles from wikitext to HTML and back. Currently all result data is stored in MySQL, which does not deal very well with the large amount of data we throw at it. This project will address this by building a Cassandra backend for the round-trip test server. This will involve working with node.js and Cassandra. A candidate will ideally have at least some node.js experience, and is interested in distributed systems and storage.
