Apache Pulsar vs. Apache Kafka 2022 Benchmark

Executive Summary

Organizations often make comparisons between Apache Pulsar and Apache Kafka based on features, capabilities, size of the community, and a number of other metrics of varying importance. This report focuses purely on comparing the technical performance based on benchmark tests.

The last widely published Pulsar versus Kafka benchmark was performed in 2020, and a lot has happened since then. In 2021, Pulsar ranked as a Top 5 Apache Software Foundation project and surpassed Apache Kafka in monthly active contributors. Pulsar also averaged more monthly active contributors than Kafka for most of the past 18 months.

These contributions led to major performance improvements for Pulsar. To measure the impact of the improvements, the engineering team at StreamNative, led by Matteo Merli, Apache Pulsar PMC Chairperson, and StreamNative CTO, performed a benchmark study using the Linux Foundation Open Messaging benchmark.
