Kafkorama — the newest member of the MigratoryData ecosystem — exposes real-time data from Apache Kafka® as Streaming APIs, enabling any developer, not just Kafka developers, to go beyond backend apps and build real-time web, mobile, and IoT apps for Kafka. For this to work at Internet scale, Kafkorama must be both fast and scalable to handle all your users and Kafka streams. In this post, we present benchmark results showing how Kafkorama scales both vertically on a single node and horizontally across a multi-node cluster — delivering 1 million messages per second to 1 million concurrent clients over WebSockets with end-to-end mean latency under 5 milliseconds.
