ApacheCon North America 2014

Apache Drill started off with the audacious goal of delivering consistent, millisecond ANSI SQL query capability across wide range of data formats. At a high level, this translates to two key requirements – Schema Flexibility and Performance.  This session will delve into the architectural details in delivering these two requirements and will share with the audience the nuances and pitfalls we ran into while developing Apache Drill.
IT will cover how Apache Drill supports schema-less data querying and how application driven schemas like JSON structures can be tackled. I will cover details on how data sources in Drill present query rewrites to the query optimizer, thus allowing complex query push-down into the data source and how Drill generates very efficient low-level code that changes according to the kind and shape of data that is processed in the moment.
