Spark SQL

Spark SQL is a technology that allows you to efficiently analyze and process large amounts of data stored in databases or data files. It provides a familiar way to ask questions about the data using a language similar to SQL, enabling you to filter, aggregate, and transform data easily. Spark SQL is part of Apache Spark, a powerful platform designed for fast, distributed computing, making it suitable for handling big data workloads quickly. Essentially, it helps organizations gain insights from vast data collections without needing complex programming, by offering a simple interface for data analysis at scale.
