What is PySpark?

Apache Spark is an open-source, distributed computing platform and collection of tools for real-time, massive data processing, and PySpark is its Python API. PySpark is a Python-based API that combines Python with the Spark framework. However, everyone knows Python is a programming language while Spark is the big data engine. As a vast data processing engine, Spark is at least 10 to 100 times quicker than Hadoop.
