This is a meetup for users of Spark (www.spark-project.org) in Austin, Texas. Spark is a high-speed Scala-based cluster programming framework which was developed at UC Berkeley. Spark is a major challeneger for Hadoop in the big data space because benchmarks show that it can outperform Hadoop by a 100x in some cases. Spark has also been accept in the Apache Incubator as of June 2013. The meetup will include introductions to the various Spark features, and case studies from current users. We will also discuss Spark related technologies,e.g., Shark.
