I like the performance and reliability of Kafka. I needed a data streaming buffer that could handle thousands of messages per second with at least one processing point for an analytics pipeline. Kafka fits this requirement very well.
Apache Kafka offers high performance and reliability, managing thousands of messages per second with scalability and fault tolerance through built-in replication. It excels as a distributed commit log, handling large-scale message processing, with versatile real-time capabilities for streaming and transactions. However, dependency issues with ZooKeeper, complex setup, lack of enterprise-grade monitoring, high memory consumption, and scalability challenges require expertise for effective deployment and management.
