Apache Spark Briefing

  1. 1. Apache Spark The Emerging Platform for Distributed Analytics July 2014 Thomas W. Dinsmore
  2. 2. What is Apache Spark? • Distributed in-memory analytics engine • Runs in standalone clusters or Hadoop • Fully compatible with Hadoop storage APIs • Runs under YARN • Top-level Apache project • Supported in all major Hadoop distros • Open source and vendor neutral Thomas W. Dinsmore
  3. 3. SAP Support Spark Timeline + + + + +2009 2010 2011 2012 2013 2014 ++ Project begins Open sourced Spark Summit 2013 Spark Summit 2013 Apache Incubator Apache Top-Level Cloudera Support MapR Support Horton Support Thomas W. Dinsmore News cascade starting late last year.
  4. 4. What problems does Spark solve?
  5. 5. Problem #1: MapReduce I/O sandbags runtime for advanced analytics. Compute Store Must persist results after each pass through data Advanced analytics often requires multiple passes through data Hadoop Storage Hadoop Storage Thomas W. Dinsmore
  6. 6. Spark Vision: Distributed in-memory platform Compute Intermediate results stay in memory. 100X performance improvement for iterative algorithms. Compute Compute Compute Hadoop Storage Thomas W. Dinsmore
  7. 7. Problem #2: Many “point” solutions for advanced analytics in Hadoop Machine ! LearningQueries Graph ! Analytics Streaming ! Analytics Thomas W. Dinsmore
  8. 8. Spark Vision: single integrated platform for advanced analytics in Hadoop. • Simplified administration • Integrated results. Thomas W. Dinsmore
  9. 9. How important is Spark?
  10. 10. Mike Olson, Cloudera: “The leading candidate for ‘successor to MapReduce’ today is Apache Spark.” Thomas W. Dinsmore
  11. 11. M.C. Srivas, MapR: “We believe Spark on Hadoop is a game changer for any business.” Thomas W. Dinsmore
  12. 12. Ben Lorica, O’Reilly Media: “The number of companies that are using Spark in production has exploded over the last year.” Thomas W. Dinsmore
