Introduction to Apache Spark and Its Core Components

Apache Spark is an open‑source general‑purpose parallel framework from UC Berkeley AMP Lab, designed as a fast, unified engine for large‑scale data processing.

Spark is currently the most popular unified batch‑and‑stream big‑data processing platform. Since the release of version 1.2 in 2014, it has become an indispensable component in the big‑data field, with rapid development and an active community. Spark’s ecosystem includes Spark SQL for batch and interactive queries, Spark Streaming for stream processing, and GraphX and MLlib for graph computation and machine learning.

As of now, the latest released version of Spark is 2.4.3.

This article is based on a recent internal Spark sharing, covering a detailed introduction to Spark RDDs and explanations of core modules such as DAGScheduler, TaskScheduler, and BlockManager.
