Apache Kafka vs CockroachDB

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.

CockroachDB is a distributed SQL database that provides horizontal scalability, strong consistency, and automatic failover for mission-critical applications. It offers PostgreSQL compatibility with the resilience of distributed systems.
