The Apache Software Foundation is an open-source, community-led foundation that is responsible for Apache Server, one of the most influential software components that drives both the Internet and enterprise computing. Two critical Apache components to the modern data stack strategy are Kafka and Spark. Apache Kafka is a distributed event store and an event streaming platform that is designed to capture streams of data and events for use in analytics. Kafka is most efficient for use with real-time analysis solutions, relying on streams of events. Apache Spark is a multilanguage engine that can be used for data engineering, data science, and machine learning. A critical component of Spark is the ability to program clusters, providing parallelism and fault tolerance. Spark assists with the curation of data within the modern data stack. It helps with pruning, cleaning, and maintaining the data, especially streamed content or batch processing. In the modern data stack architecture, Apache Kafka interacts with the system through Spark.
