Answer / Vishwajeet Kumar
Apache Spark is an open-source, distributed computing system that provides a fast and general engine for big data processing. It allows for easy processing of large datasets in batch and real-time streams using Python, Java, Scala, or SQL APIs. The evolution of Apache Spark was motivated by the need to address the limitations of MapReduce for real-time and iterative data processing tasks. Spark offers a more flexible and efficient approach, with support for various data structures like RDDs and DataFrames/Datasets, and features like transformations that are lazily evaluated and optimized.
