Caching

Cycle ORM does not provide caching abilities on the core level, however, it provides multiple points at which caching can be integrated.

#Caching the Selection

In order to cache the selected entities and their relations, you can use the method fetchData of Cycle\ORM\Select.

$userData = $userRepository->select()->load('profile')->fetchData();

The resulted array will contain all raw entity data (table columns) with typecasted values. You can then store this information in a cache.

Make sure that all custom column types are serializable.

In order to unpack cached information simply push given data into Cycle\ORM\Iterator object:

$users = new Iterator($orm, User::class, $userData);

#Caching in Heap

Every loaded entity will be automatically placed into the Heap. The primary method to check if an object is already located in the heap is find:

$u = $orm->getHeap()->find(User::class, 'id', 1);

Implementing your own Heap might provide you an ability to automatically store some objects in the cache.

Cache invalidation can be achieved using a custom Mapper (persister) implementation by altering methods queueUpdate and queueDelete.
