Apache Kafka vs Couchbase

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.

Couchbase is a distributed NoSQL database providing high performance, high availability, and flexible data models for modern applications. It combines document-oriented flexibility with traditional database reliability.
