Optimizing Kafka

Yeva Byzek explains different tuning options available within Apache Kafka:

Without needing to make any changes to Kafka configuration parameters, you can setup a development Kafka environment and test basic functionality. Yet the fact that Kafka runs straight off the shelf does not mean you won’t want to do some tuning before you go into production. The reason to tune is that different use cases will have different sets of requirements that will drive different service goals. To optimize for those service goals, there are Kafka configuration parameters that you should change. In fact, the Kafka design itself provides configuration flexibility to users, and to make sure your Kafka deployment is optimized for your service goals, you absolutely should investigate tuning the settings of some configuration parameters and benchmarking in your own environment. Ideally, you should do that before you go to production, or at least before you scale out to a larger cluster size.

We have written a white paper to help you identify those service goals, configure your Kafka deployment to optimize for them, and ensure that you are achieving them through monitoring.

Crossing The Streams With Kafka

Himani Arora shows how to join two Kafka streams together: KStream-KStream Join It is a sliding window join, that means, all tuples close to each other with regard to time are joined. Time here is the difference up to size of the window. These joins are always windowed joins because otherwise, the size of the internal state […]

Benchmarking Streaming Systems

Burak Yavuz shares a benchmark of Spark Streaming versus Flink and Kafka Streams: At Databricks, we used Databricks Notebooks and cluster management to set up a reproducible benchmarking harness that compares the performance of Apache Spark’s Structured Streaming, running on Databricks Unified Analytics Platform, against other open source streaming systems such as Apache Kafka Streams and Apache Flink. In particular, we used the following […]
