Apache Kafka vs Memcached

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.

Memcached is distributed in-memory caching system used to reduce database load by caching frequently accessed data. It provides comprehensive features for databases workflows. The tool is actively maintained with regular updates and strong community/vendor support.
