Configure cache

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.

Configure a cache resource

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

Field	Description
name	Name of the cache that you're creating. If empty, the custom resource (CR) name is used.
hazelcastResourceName	The name of the Hazelcast resource.
backupCount	Count of synchronous backups.
asyncBackupCount	Count of asynchronous backups.
keyType	Fully qualified class name of the cache key type.
valueType	Fully qualified class name of the cache value type.
persistenceEnabled	When enabled, the cache data will be persisted.
inMemoryFormat	Format options for storing the data in cache.

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

yaml

apiVersion: hazelcast.com/v1alpha1
kind: Cache
metadata:
  name: cache-sample
spec:
  hazelcastResourceName: hazelcast
  backupCount: 1
  asyncBackupCount: 0
  inMemoryFormat: NATIVE
  keyType: java.lang.Object
  valueType: java.lang.Object
  persistenceEnabled: false

After creating the Cache resource, you can check its status:

shell

kubectl get cache cache-sample -o wide

NAME           STATUS    HAZELCAST-RESOURCE   MESSAGE
cache-sample   Success   hazelcast
