Apache Kafka Benchmark: Partitions, Replication, and Latency

🍽️ Dish of the Day: Apache Kafka Benchmark In this video, Apache Kafka goes into the kitchen — and the cluster turns into a high-performance restaurant. Step by step, you’ll learn how to build a complete test “menu” using only native binaries (kafka-producer-perf-test.sh, kafka-consumer-perf-test.sh, kafka-e2e-latency.sh) to measure throughput, end-to-end latency, the impact of partitions, and replication factor. 🥗 Starter – Cluster Mise en Place Prepare test topics with different combinations of partitions and replication factors. Make sure disk, CPU, and network are ready for the “service” by running baseline I/O tests and setting up real-time monitoring tools (iostat, iftop, htop, etc.). Helps identify disk I/O performance: bash Quick 1GB file test dd if=/dev/zero of=/tmp/tmpfile bs=1M count=1024 conv=fsync dd if=/tmp/tmpfile of=/dev/null bs=1M count=1024 rm /tmp/tmpfile 🍝 Main Course – Throughput Feast Learn how to use kafka-producer-perf-test.sh to measure throughput per partition and uncover the true cost of replication (RF=1 vs RF=3). Discover how to calculate the minimum number of partitions needed to reach a specific MB/s goal, turning business requirements into clear technical decisions. 🍷 Pairing – End-to-End Latency Run end-to-end latency tests with kafka-e2e-latency.sh, and understand average, P95, P99, and P99.9 results to see whether your “service” is running smoothly or getting stuck in the kitchen. Compare acks, message sizes, and producer configurations to balance throughput and reliability — without wasting resources. 🍰 Dessert – Monitoring and Troubleshooting Learn how to cross-check Kafka results with disk, CPU, memory, and network metrics to find the true bottleneck (not just the “usual suspect”). Find out which producer, consumer, and broker metrics deserve a permanent spot on your production observability menu. 📦 Free Tool: kafka-perf-test To speed things up, check out the kafka-perf-test repository — it includes Docker Compose, Bash scripts, and a Python implementation that automates the tests and generates interactive HTML reports for visual analysis.
