Who is this presentation for?

  • Data scientists, data architects, Hadoop users, and business analysts

Prerequisite knowledge

  • Familiarity with Hadoop applications and data cleansing and preparation

What you'll learn

  • Learn best practices for deploying Hadoop applications to support data exploration in an enterprise scale


Organizations deploying Hadoop are storing, organizing, processing, and analyzing more data than ever before, and the number of analytic applications natively integrating with Hadoop has grown rapidly in the last few years. Consequently, there are often hundreds or thousands of business and data analysts that leverage Hadoop clusters to explore, wrangle, visualize, and operationalize data for diverse use cases. As cluster utilization increases, however, maintaining performance of both exploratory and production use cases becomes critical.

Sean Kandel and Kaushal Gandhi share best practices for building and deploying Hadoop applications to support large-scale data exploration and analysis across an organization and demonstrate techniques to amortize exploratory workloads across clients to scale deployments while limiting performance degradation. Along the way, Sean and Kaushal explain how to flexibly compile queries across multiple runtime engines to optimize both data analytic and transformation queries and compare benchmarks for multiple architectures, demonstrating the effects of these techniques in data lake initiatives.
