Our goal with Apache Spark is very simple: provide the best platform for computation on big data. We do this through both a powerful core engine and rich libraries for useful analytics tasks. Today, we are excited to announce the release of Spark 0.9.0. This major release extends Spark’s libraries and further improves its performance and usability. Spark 0.9.0 is the largest release to date, with work from 83 contributors, who submitted over 300 patches.
