Configuring Kubernetes Kit

When a session is serialized, Kubernetes Kit inspects classes for transient fields that can be injected during deserialization (see session replication).

Kubernetes Kit provides two properties to limit the packages to be inspected. The include-package property defines all of the packages that should be inspected. If this is undefined, all packages are assessed. For this reason, it’s recommended that you specify the top-level package for your application in the include-packages property.

The exclude-package property lists packages that should not be assessed.

The service-name property defines the name of the Hazelcast service deployment within a cluster.

The optional namespace property is used when the Hazelcast service is deployed in a namespace other than default.

This property defines the name of the Redis service deployment within a cluster.

The backend session expiration policy allows you to define an expiration timeout for the backend stored session. By default, no expiration is set. However, expiration can be activated by setting the vaadin.kubernetes.backend-session-expiration-tolerance property. The property defines the amount of time to be added to the HTTP session timeout to determine the expiration of the backend session. If a time unit is not given, milliseconds is assumed. Another option is to provide a custom SessionExpirationPolicy bean, which allows you to define a custom expiration timeout, independent of the HTTP session timeout value.
