Apache Kafka vs Cassandra

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.

Apache Cassandra is an open-source distributed NoSQL database designed for handling large amounts of data across commodity servers with high availability and no single point of failure. It uses a masterless ring architecture with tunable consistency.
