The Sparkline BI Accelerator is a Spark native Business Intelligence Stack geared towards providing fast ad-hoc querying over a Logical Cube(aka Star-Schema). It simplifies how enterprises can provide an ad-hoc query layer on top of a Hadoop/Spark(Big Open Data Stack).

  • we provide the ad-hoc query capability by extending the Spark SQL layer, through SQL extensions and an extended Optimizer(both logical and Physical optimizations).
  • we use OLAP indexing vs. pre-materialization as a technique to achieve query performance. OLAP Indexing is a well-known technique that is far superior to materialized views to support ad-hoc querying. We utilize another Open-Source Apache licensed Big Data component for the OLAP Indexing capability.
