Fast and Reliable Apache Spark SQL EngineCheng Lian Databricks

Building the next generation Spark SQL engine at speed poses new challenges to both automation and testing. At Databricks, we are implementing a new testing framework for assessing the quality and performance of new developments as they produced. Having more than 1,200 worldwide contributors, Apache Spark follows a rapid pace of development. At this scale, new testing tooling such as random query and data generation, fault injection, longevity stress, and scalability tests are essential to guarantee a reliable and performance Spark later in production. By applying such techniques, we will demonstrate the effectiveness of our testing infrastructure by drilling-down into cases where correctness and performance regressions have been found early. In addition, showing how they have been root-caused and fixed to prevent regressions in production and boosting the continuous delivery of new features.
