Loaders facilitate loading of data into the cache from a third-party data source. When an application does a lookup for a key in a region and it does not exist, GemFire checks to see if any loaders are available for the region in the system and invokes them to get the value for the key into the cache.

A cache loader is defined in the RegionAttributesTKey, TValue.

When [!:Region.Get] is called for a region entry that has a null value, the [!:ICacheLoader.Load] method of the region's cache loader is invoked. The Load method creates the value for the desired key by performing an operation such as a database query.
