Use Apache Gradle to Build and Automate KSQL and Kafka Streams

Session Level: Intermediate

KSQL is an easy-to-use and easy-to-understand streaming SQL engine for Apache Kafka built on top of Kafka Streams. The ability to write streaming applications using only SQL makes Apache Kafka available to a whole range of new developers and potential use cases, either as a stand-alone solution, or as a single component to a broader Kafka Streams implementation. Inspired by a customer project now in production, experience the lifecycle of a streaming application developed using KSQL and Kafka Streams. With Apache Gradle as our build framework, we’ll explore the open-source Gradle plugin we built during this project to improve developer efficiency and automate the deployment of KSQL pipelines, user-defined functions, and Kafka Streams microservices.

We’ll demonstrate the deployment process live, and discuss design decisions around incorporating SQL-based processes into an overall streaming application.

Key Takeaways

1. KSQL is a natural choice for expressing data-driven applications, but it may not naturally fit into established DevOps processes and automations.

2. We built an open-source Gradle plugin to handle all aspects of deploying a Kafka-based streaming application: KSQL pipelines, KSQL user-defined functions, and Kafka Streams microservices.

3. KSQL pipelines can be deployed using either a server start script, or the KSQL REST API, and our Gradle plugin fully supports both options.
