Using kafka mockconsumer. 1. overview. in this tutorial, we’ll explore the mockconsumer, one of kafka ‘s consumer implementations. first, we’ll discuss what are the main things to be considered when testing a kafka consumer. then, we’ll see how we can use mockconsumer to implement tests. 2. testing a kafka consumer.

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. 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.

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. All that leaves us to so is send the message and tidy up the connection which we do using: producer.send(producerrecord); producer.close(); and that is it, your message and headers posted to your kafka topic. all you need to do is build the load profile around the jsr223 sampler and you have a performance test.
