Data coming from entityTypeManager->getStorage is cached data?

Question

I am working on one Drupal 8.3 site. I created my own custom Authentication provider for REST API authorisation.

Following are the "authenticate" method sample code.

/**
   * {@inheritdoc}
   */
  public function authenticate(Request $request) {
      try {

          $uid = 1;// passing 1 for testing.

          $accounts = $this->entityTypeManager->getStorage('user')->loadByProperties(array('uid' => $uid, 'status' => 1));
          $account = reset($accounts);
          if ($account) {
              return $this->entityTypeManager->getStorage('user')->load($uid);
          }
      } 
      return [];
  }

My doubt here is "$this->entityTypeManager->getStorage" is getting data from cache table. Or everytime it connect to db and generate response?

Answer 1

load() and loadMultiple() are cached, loadByProperties() is a shortcut for an entity query + load, the entity query is not cached.

Do not use loadByProperties() if you know the entity ID.

Answer 2

For anyone coming across this issue;

You can also use the entity resetCache without passing an entity ID parameter since the resetCache method can accept empty parameters. See documentation on: EntityStorageBase::resetCache

$entity_storage = \Drupal::entityTypeManager()->getStorage('YOUR_ENTITY_NAME');
$entity_storage->resetCache(); // reset entity to clear cache
$results = $entity_storage->loadByProperties(['uid' => $uid, 'status' => 1]); // load entity data
return $results;
