Kafkorama benchmark: 1M msg/s to 1M clients with <5 ms mean latency (on 1 node)

[michelrotaru]

Kafkorama exposes real-time data from Apache Kafka as Streaming APIs for web, mobile, and IoT apps.

We just benchmarked it:

- 1M messages/second delivered to 1M concurrent WebSocket clients

- Mean end-to-end latency <5 ms (30-minute runs, >1B messages each)

- 609 MB/s outgoing throughput using 512-byte messages

- Achieved both on a single node (vertical) and across a cluster (horizontal) with linear scalability

can connect to any database provider?

Kafkorama itself doesn't talk directly to databases — it integrates natively with Kafka. If your DB streams into Kafka (via Debezium or connectors), Kafkorama can expose that data to users, and vice-versa. With the Kafkorama SDKs you can also connect directly to any database (or other system) and either push data into Kafkorama or get data from it, even without Kafka.
