The first step to set up the Grouping API is to enable groups. In Red Hat JBoss Data Grid, groups are enabled declaratively or programmatically as follows:
Declaratively Enable Groups
Use the following configuration to enable groups using XML:
<clustering>
<hash>
<groups enabled="true" />
</hash>
</clustering>
Programmatically Enable Groups
Use the following to enable groups programmatically:
Configuration c = new ConfigurationBuilder().clustering().hash().groups().enabled().build();
