Catalyst Optimizer refresh

As noted in Chapter 1, Understanding Spark, one of the primary reasons the Spark SQL engine is so fast is because of the Catalyst Optimizer. For readers with a database background, this diagram looks similar to the logical/physical planner and cost model/cost-based optimization of a relational database management system (RDBMS):

The significance of this is that, as opposed to immediately processing the query, the Spark engine's Catalyst Optimizer compiles and optimizes a logical plan and has a cost optimizer that determines the most efficient physical plan generated.

Note

As noted in earlier chapters, while the Spark SQL Engine has both rules-based and cost-based optimizations that include (but are not limited to) predicate push down and column pruning. Targeted for the Apache Spark 2.2 release, the jira item [SPARK-16026] Cost-based Optimizer Framework at https://issues.apache.org/jira/browse/SPARK-16026 is an umbrella ticket to implement a cost-based optimizer framework...

Drabas

Tomasz Drabas is a Data Scientist working for Microsoft and currently residing in the Seattle area. He has over 12 years' international experience in data analytics and data science in numerous fields: advanced technology, airlines, telecommunications, finance, and consulting. Tomasz started his career in 2003 with LOT Polish Airlines in Warsaw, Poland while finishing his Master's degree in strategy management. In 2007, he moved to Sydney to pursue a doctoral degree in operations research at the University of New South Wales, School of Aviation; his research crossed boundaries between discrete choice modeling and airline operations research. During his time in Sydney, he worked as a Data Analyst for Beyond Analysis Australia and as a Senior Data Analyst/Data Scientist for Vodafone Hutchison Australia among others. He has also published scientific papers, attended international conferences, and served as a reviewer for scientific journals. In 2015 he relocated to Seattle to begin his work for Microsoft. While there, he has worked on numerous projects involving solving problems in high-dimensional feature space.
