pruning, or the automatic removal of unknown fields in objects sent to a Kubernetes API. An "unknown" field is one that is not specified in the OpenAPI validation schema. This behavior is already in place for native resources and ensures only data structures specified by the CRD developer are persisted to etcd. It will be available as a beta feature in Kubernetes 1.15.

Pruning is activated by setting `spec.preserveUnknownFields: false` in the CustomResourceDefinition. A future apiextensions.k8s.io/v1...

            // When
            int bytesWritten = copy.encode(buffer, startIndex);

            // Then
            assertEquals(HEADER_SIZE, bytesWritten);

            // Verify source key is copied correctly
            for (int i = 0; i < SOURCE_KEY_SIZE; i++) {
                assertEquals(sourceKey[i], buffer[startIndex + i], "Source key byte at position " + i + " doesn't match");
            }
        }
