ksqlDB is built on Kafka Streams, a robust stream processing framework that is part of Apache Kafka®. You can use ksqlDB and Kafka Streams together in your event streaming applications. ksqlDB gives you a query layer for building event streaming applications on Kafka topics.

ksqlDB is a new kind of database purpose-built for stream processing apps, allowing users to build stream processing applications against data in Apache Kafka® and enhancing developer productivity.

 It consolidates the many components found in virtually every stream processing architecture.

That is important because almost all streaming architectures today are piecemeal solutions cobbled together from different projects. At a minimum, you need a subsystem to acquire events from existing data sources, another to store them, another to process them, and another to serve queries against aggregated materializations. Integrating each subsystem can be difficult.
