Hazelcast IMDG Standard Support has expired. Extended support for version 4.1 ends in April 2024. Extended support for version 4.2 ends in September 2024.

We recommend that you try Hazelcast Platform.

In Hazelcast Platform, we’ve combined the in-memory storage of IMDG with the stream processing power of Jet. Find out more in our Platform documentation.

Using Pro and Enterprise editions

Hazelcast IMDG offers two commercially licensed editions: Pro and Enterprise. The supported features differ in your Hazelcast setup according to the license type you own.

See also here for a more detailed feature comparison between the editions.

Setting Up License Key

Hazelcast IMDG Pro and Enterprise license keys are required only for members. You do not need to set a license key for your Java clients for which you want to use the Pro and Enterprise features.

To use Hazelcast IMDG Pro or Enterprise, you need to set the provided license key using one of the configuration methods shown below.

  • XML

  • YAML

  • Java

  • Spring XML

  • JVM System Property

<!-- Add the below line to any place you like in the file `hazelcast-default.xml`. -->

    <license-key>Your Enterprise License Key</license-key>
# Add the below line to any place you like in the file `hazelcast-default.yaml`.

  license-key: Your Hazelcast Enterprise or Enterprise HD License Key
// Programmatic configuration.

Config config = new Config();
config.setLicenseKey( "Your Enterprise License Key" );
    <hz:license-key>Your Enterprise License Key</hz:license-key>
-Dhazelcast.enterprise.license.key=Your Enterprise License Key

For monitoring information such as expiration date of your license key see License Information.

<Name of the Hazelcast edition>#<Count of the Members>#<License key>

The strings before the <License key> is the human readable part. You can use your license key with or without this human readable part. So, both the following example license keys are valid:
