[Workshop] Stream-Verarbeitung leicht gemacht mit Flink | Jetzt registrieren
As always, we bring you news, updates and recommended content from the hectic world of Apache Kafka® and stream processing.
Sometimes it seems that in Apache Kafka every improvement is preceded by an involved KIP process. This month we’ve merged a great patch that improved the 99% latency of Kafka without requiring user visible changes: https://issues.apache.org/jira/browse/KAFKA-4614. Not only does it make a fast system even faster, the JIRA itself is worthy of study. I wish all JIRAs included this level of research.
Some important improvements do require KIPs. Here is what we’ve seen in active discussions this month:
Notable Blogs and Presentations:
We are proud to announce the release of Apache Kafka 3.9.0. This is a major release, the final one in the 3.x line. This will also be the final major release to feature the deprecated Apache ZooKeeper® mode. Starting in 4.0 and later, Kafka will always run without ZooKeeper.
In this third installment of a blog series examining Kafka Producer and Consumer Internals, we switch our attention to Kafka consumer clients, examining how consumers interact with brokers, coordinate their partitions, and send requests to read data from Kafka topics.
