KSQL allows to build event streaming applications from Apache Kafka® topics by using SQL statements and queries. KSQL is built on Kafka Streams, so a KSQL application communicates with a Kafka cluster like any other Kafka Streams application.

Using Adapter for Apache Kafka, Integration Server clients can create and run services to perform KSQL operations such as create streams or tables, select from streams or tables, insert values into streams or tables and so on.
