The rapid growth in data volumes requires new computer systems that scale out across hundreds of machines. While early frameworks, such as MapReduce, handled large-scale batch processing, the demands on these systems have also grown. Users quickly needed to run (1) more interactive ad-hoc queries, (2) more complex multi-pass algorithms (e.g. machine learning and graph processing), and (3) real-time processing on large data streams. In this talk, we present a single abstraction, resilient distributed datasets (RDDs) that supports all of these emerging workloads by providing efficient and fault-tolerant in-memory data sharing. We have used RDDs to build a stack of computing systems including the Spark parallel engine, Shark SQL processor, and Spark Streaming engine. Spark and Shark can run machine learning algorithms and interactive queries up to 100x faster than Hadoop MapReduce, while Spark Streaming enables fault-tolerant stream processing at significantly higher scales than were possible before. These systems, along with several resource allocation and scheduling algorithms we have developed along the way, have been used in multiple industry and research applications, and have a growing open source community with 14 companies contributing in the past year.
