  4. 4. Spark Camp: Ask Us Anything Fri, Feb 20 2:20pm-3:00pm
 strataconf.com/big-data-conference-ca-2015/ public/schedule/detail/40701 Join the Spark team for an informal question and answer session. Several of the Spark committers, trainers, etc., from Databricks will be on hand to field a wide range of detailed questions. Even if you don’t have a specific question, join 
 in to hear what others are asking!
  5. 5. Apache Spark Advanced Training Feb 17-19 9:00am-5:00pm
 strataconf.com/big-data-conference-ca-2015/ public/schedule/detail/39399 Sameer Farooqui leads this new 3-day training program offered by Databricks and O’Reilly Media at Strata + Hadoop World events worldwide. Participants will also receive limited free-tier accounts on Databricks Cloud. Note: this sold out early, so if you want to attend it at Strata EU, sign up quickly!
  6. 6. Spark Developer Certification
 Fri Feb 20, 2015 10:40am-12:40pm • http://oreilly.com/go/sparkcert • defined by Spark experts @Databricks • assessed by O’Reilly Media • establishes the bar for Spark expertise
  7. 7. • 40 multiple-choice questions, 90 minutes • mostly structured as choices among code blocks • expect some Python, Java, Scala, SQL • understand theory of operation • identify best practices • recognize code that is more parallel, less memory constrained ! Overall, you need to write Spark apps in practice Developer Certification: Overview 7
  8. 8. Even More Apache Spark!

  9. 9. Keynote: New Directions for Spark in 2015 Fri Feb 20 9:15am-9:25am
 strataconf.com/big-data-conference-ca-2015/ public/schedule/detail/39547 As the Apache Spark userbase grows, the developer community is working 
 to adapt it for ever-wider use cases. 2014 saw fast adoption of Spark in the enterprise and major improvements in its performance, scalability and standard libraries. In 2015, we want to make Spark accessible to a wider 
 set of users, through new high-level APIs for data science: machine learning pipelines, data frames, and R language bindings. In addition, we are defining extension points to let Spark grow as a platform, making it easy to plug in data sources, algorithms, and external packages. Like all work on Spark, 
 these APIs are designed to plug seamlessly into Spark applications, giving users a unified platform for streaming, batch and interactive data processing. Matei Zaharia – started the Spark project at UC Berkeley, currently CTO of Databricks, SparkVP at Apache, and an assistant professor at MIT

  13. 13. 13 A Brief History: Functional Programming for Big Data circa late 1990s: 
 explosive growth e-commerce and machine data implied that workloads could not fit on a single computer anymore… notable firms led the shift to horizontal scale-out 
 on clusters of commodity hardware, especially 
 for machine learning use cases at scale

  17. 17. Developed in 2009 at UC Berkeley AMPLab, then open sourced in 2010, Spark has since become 
 one of the largest OSS communities in big data, with over 200 contributors in 50+ organizations spark.apache.org “Organizations that are looking at big data challenges –
 including collection, ETL, storage, exploration and analytics –
 should consider Spark for its in-memory performance and
 the breadth of its model. It supports advanced analytics
 solutions on Hadoop clusters, including the iterative model
 required for machine learning and graph analysis.” Gartner, Advanced Analytics and Data Science (2014) 17 A Brief History: Spark
