function hook_entity_query_alter

Alter or execute an Drupal\Core\Entity\Query\EntityQueryInterface.

Parameters

\Drupal\Core\Entity\Query\QueryInterface $query: Note the $query->altered attribute which is TRUE in case the query has already been altered once. This happens with cloned queries. If there is a pager, then such a cloned query will be executed to count all elements. This query can be detected by checking for ($query->pager && $query->count), allowing the driver to return 0 from the count query and disable the pager.
