Apache Kafka vs MongoDB

Apache Kafka is an open-source distributed event streaming platform used for building real-time data pipelines and streaming applications. Originally developed at LinkedIn, it provides high-throughput, fault-tolerant publish-subscribe messaging with persistent storage. Kafka supports stream processing through Kafka Streams and ksqlDB.

MongoDB is document-oriented NoSQL database that stores data in flexible JSON-like structures. It provides comprehensive features for databases workflows. The tool is actively maintained with regular updates and strong community/vendor support.
