When I was a child, I used to lie on the bed and gaze for a long time at the patterns on an old Soviet rug, seeing animals and fantastical figures within them. Now, I more often look at code, but similar images still emerge in my mind. Like on the rug, these images form repetitive patterns. They can be either pleasing or repulsive. Today, I want to tell you about one such unpleasant pattern

Using Testcontainers has radically improved the process of working with test scenarios. Thanks to this tool, creating environments for integration tests has become simpler (see the article Isolation in Testing with Kafka). Now, we can easily launch containers with different versions of databases, message brokers, and other services. For integration tests, Testcontainers has proven indispensable. Although load testing is less common than functional testing, it can be much more enjoyable. Studying graphs and analyzing the

In this article, I want to share my experience with creating a native image for EmbeddedKafka using GraalVM. Utilizing this image in integration tests not only speeds up the execution of test scenarios but also reduces memory consumption. Interestingly, when compared to using confluentinc/cp-kafka in Testcontainers, there is a noticeable difference in both speed and memory usage — and it’s not in favor of the latter. EmbeddedKafka, Testcontainers, GraalVM A brief overview of the key
