// fetch your Cache
$cache = $this->cacheManager->getCache('My_Cache');

$entity = new \My\Domain\Model\Entity();
$entity->setName('Foo');
$this->persistenceManager->update($entity);

$identifier = 'MyOutputThatDependsOnThatEntity' . $this->cacheIdentityService->getIdentifierByObject($entity);

if (!$cache->has($identifier)) {
	// Really time-consuming and complex rendering that depends on that entity
	$output = $entity->getName();
	$cache->set($identifier, $output);

对于每个实体插入/更新/删除，将为该实体存储一个时间戳，并且可以从cacheIdentityService获取该时间戳来获取标识符，以缓存需要为该实体的版本/状态唯一的数据。
