You can easily scale the load by increasing the number of vus. for example, the following command uses 500 vus to load test for a minute: . k6 run vus 500 duration 1m test script.js. if you are new to k6, check out how to configure the load options in the script or run a stress test with k6. 2. dependencies. of course, we’ll need to add the standard spring kafka dependency to our pom.xml: then we’ll need two more dependencies specifically for our tests. first, we’ll add the spring kafka test artifact: and finally we’ll add the testcontainers kafka dependency, which is also available over on maven central:. Increase fetch size. another way to optimize consumers is by modifying fetch.min.bytes and fetch.max.wait.ms to wait for larger payload batches before returning the records to the consumer. in this example, the consumer waits for a minimum of 5kb of data or 500ms before fetching.

One of the critical metrics to track for kafka consumers is the lag, which is the delta between the last message produced and the last message consumed. you can track this using kafka’s built in command line tools: bin kafka consumer groups.sh bootstrap server localhost:9092 describe group your consumer group. The kafka performance test scripts allow us to generate and consume high volumes of data through your kafka cluster in order to measure it's performance characteristics such as throughout and latency. the tests we run using these scripts can be configured to match your real workloads, including setting the number and frequency of messages.
