Apache Spark is a unified analytics engine for big data processing, with built-in modules for streaming, SQL, machine learning, and graph processing.
Apache Spark is a data processing system that can perform tasks simultaneously on very large databases rapidly and can also spread data processing tasks, either on its own or in combination with other distributed computing resources, through multiple devices. These two characteristics are fundamental to the worlds of big data analytics, which need vast computational power to be mobilized to smash through massive data stores.
