Hazelcast offers a specification-compliant JCache implementation. The Hazelcast JCache implementation is 100% TCK (Technology Compatibility Kit) compliant and therefore passes all specification requirements. You can create and configure JCache using the Cache custom resource.

Configuring a Cache Resource

You can use any of the following configuration options in the Cache resource. For more information, see the API Reference.

Example Configuration

The following Cache custom resource creates a cache configuration for the Hazelcast custom resource that is defined in the hazelcastResourceName field.

Example configuration
