WSO2 provides Hazelcast Community Edition as its default clustering engine. For clustering on a secure channel (i.e., secure Hazelcast), you have to use Hazelcast Enterprise and this is a commercial version of Hazelcast. To integrate with Hazelcast Enterprise, there are provisions to provide license key under clustering configurations. Advanced users can fine-tune Hazelcast by creating a <PRODUCT_HOME>/repository/conf/hazelcast.properties file and adding the relevant Hazelcast properties as described in the Hazelcast Advanced Configuration Properties documentation. If you use Hazelcast Enterprise Edition or Hazelcast Management Center, see the Hazelcast documentation for details on configuring those products and also Advanced Configurations and Information for further details.
