3.3. Configure the Grouping API
Use the following steps to configure the Grouping API:
- Enable groups using either the declarative or programmatic method.
- Specify either an intrinsic or extrinsic group. For more information about these group types, see Section 3.1, “Grouping API Operations”
- Register all specified groupers.
3.3.1. Enable Groups
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();
