Hackathon Topics

u  Building a POC around using SparkR on Amazon EC2 as

a computational backend for tranSMART 1.3

u  Improving the visual analytics in tranSMART, by updating

or adding analytics workflows in the SmartR plugin

4

Apache Spark

u  Largest and most active open source project in data

science as of this year

u  Seen by many as a ‘replacement’ for Hadoop

[MapReduce] in the big data area

u  Implements lessons learned from Hadoop; built from the

ground up as a framework support data scientists

u  Core concept: in memory datasets & lazy evaluation

Hackathon Goal: SparkR integration

u  Task: Integrate Spark with tranSMART database, via the

implementation of Spark RDD interface in tranSMART core API

u  Goal: Demonstrate scalability on compute side (scalability on

database remains limited because of relational database

paradigm)

u  Benefit: Can use Spark compatible applications on top of

tranSMART (e.g. machine learning, big data analytics tools etc.)
