Welcome to the Hazelcast Jet Reference Manual. This manual includes concepts, instructions, and samples to guide you on how to use Hazelcast Jet to build applications.

Hazelcast Jet is a distributed computing platform. It supports both finite datasets (batch processing) and infinite streams with continuous operators. With Hazelcast In-Memory Data Grid (IMDG) providing storage functionality, Hazelcast Jet performs data-local parallel execution, enabling data-intensive applications to operate in real time. Using directed acyclic graphs (DAG) to model relationships between individual steps in the data processing pipeline, Hazelcast Jet is simple to deploy. Hazelcast Jet is an Apache 2 licensed open source project. Please also refer to the Hazelcast Jet website for information on its features, use cases and performance considerations.

As the reader of this manual, you must be familiar with the Java programming language and you should have installed your preferred Integrated Development Environment (IDE).
