This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar. Understand more

If you're using Apache Kafka and building stream-processing applications, ksqlDB is a great framework for writing simple applications using SQL-like statements. ksqlDB is not a traditional SQL database. However, it allows you to use lightweight SQL-like statements to build new Kafka streams or tables on top of the existing Kafka topics. The queries can pull data, similar to reading from a traditional database, or push results to the application when incremental changes occur. You can choose to run it as a standalone server natively as part of your existing Apache Kafka installation or as a fully managed service on Confluent Cloud. We're using ksqlDB in simple data-processing use cases. In more complex use cases, where an application requires programming code beyond algebraic SQL queries, we continue to use data-processing frameworks such as Apache Spark or Apache Flink on top of Kafka. We recommend experimenting with ksqlDB in scenarios where the simplicity of the application allows it.
