Remarks
Firstly, the GetObjectByKey method searches in memory for the object with the specified value of the key property. If such an object is found, it is not reloaded. To get the up-to-date object from storage the alwaysGetFromDb parameter must be set to true.
Note
The GetObjectByKey method does not find objects until they are saved to a data store.
