Apache Spark
Apache Spark is an open-source, distributed computing system designed for large-scale data processing. It provides an interface for programming entire clusters with implicit data parallelism and fault tolerance, supporting batch processing, real-time streaming, machine learning, and graph processing. Spark is known for its in-memory computing capabilities, which significantly speed up data processing compared to disk-based systems like Hadoop MapReduce.
Developers should learn Apache Spark when working with big data analytics, ETL (Extract, Transform, Load) pipelines, or real-time data streaming applications, as it offers high performance and scalability for processing terabytes to petabytes of data. It is particularly useful in industries like finance, e-commerce, and healthcare for tasks such as fraud detection, recommendation systems, and log analysis, where fast data processing is critical.
