Get Started

Get Started

These guides demonstrate how to get started quickly with Hazelcast IMDG and Hazelcast Jet.

Hazelcast IMDG

Learn how to store and retrieve data from a distributed key-value store using Hazelcast IMDG. In this guide you’ll learn how to:

  • Create a cluster of 3 members.
  • Start Hazelcast Management Center
  • Add data to the cluster using a sample client in the language of your choice
  • Add and remove some cluster members to demonstrate data balancing capabilities of Hazelcast

Hazelcast Jet

Learn how to build a distributed data processing pipeline in Java using Hazelcast Jet. In this guide you’ll learn how to:

  • Install Hazelcast Jet and form a cluster on your computer
  • Build a simple pipeline that receives a stream of data, does some calculations and outputs some results
  • Submit the pipeline as a job to the cluster and observe the results
  • Scale the cluster up and down while the job is still running

No Complex Middleware

You want to build the data pipeline (streaming or batch) without installing complex middleware.

The quickest way to learn how to use Hazelcast Jet is to start up a Jet cluster directly from your Java application and run some distributed data processing jobs. Check out the “Getting Started Guide.” Then we suggest you enroll for free Hazelcast training and take the “Stream Processing Essentials” course.

If you’re still in doubt whether continuous data processing is what you need for your use case, listen to a podcast recorded by Jet’s lead engineer, or read the Reference Guide to Stream Processing.

Do you still wonder what Jet is and how it fits into Hazelcast? Compare Jet with popular tools such as or Spark and read more about the architecture and programming model.

If you prefer learning by doing, we definitely recommend browsing the demo repository. Demos are self-contained and easy to run, so you can tweak and extend them. Demos are inspired by production Jet deployments.

Once you feel ready to begin looking at the wider set of features, there are extensive examples on github.
