Want to try Hazelcast 5.0 beta?

We’ve combined the in-memory storage of IMDG with the stream processing power of Jet to bring you an all new Hazelcast platform.

Configuring with System Properties

You can use system properties to configure some aspects of Hazelcast. You set these properties as name and value pairs through declarative configuration, programmatic configuration or JVM system property. Following are examples for each option.

Declarative Configuration:

  • XML

  • YAML

<hazelcast>
    ...
    <properties>
        <property name="hazelcast.property.foo">value</property>
    </properties>
    ...
</hazelcast>
hazelcast:
    ...
    properties:
      hazelcast.property.foo: value
    ...

Programmatic Configuration:

Config config = new Config() ;
config.setProperty( "hazelcast.property.foo", "value" );

Using JVM’s System class or -D argument:

System.setProperty( "hazelcast.property.foo", "value" );

or

java -Dhazelcast.property.foo=value

You will see Hazelcast system properties mentioned throughout this Reference Manual as required in some of the chapters and sections. All Hazelcast system properties are listed in the System Properties appendix with their descriptions, default values and property types as a reference for you.
