> A modified version of the default local cache provider which will run a lookup on the backend storage if a requested type is not found in the cache, and load it in the cache and return it if it's found. This lazy-loading cache would cover the case where new types are registered, not the case where existing types are modified, while avoiding the deployment/maintenance and performance impact of a distributed cache in an HA environment.
