Apache Kafka vs Cloud Firestore

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.

Cloud Firestore is Google's fully-managed NoSQL database for storing and syncing data in real-time across web, mobile, and server applications. It provides powerful querying, automatic scaling, and seamless integration with Firebase services.
