>
> Entity:
> - An entity would contain a model and defines it's complex relationship with
> other models
> - Differing from a model entities gets satisfied only when all the required
> data is loaded
> - Entity must ensure REST API backward compatibility
> Loader
> - Loaders are supposed to load an entity(s), like stores fetch model(s)
> - Loaders must take case of caching
> - In pages like 'All DAGs' without a limit. If tables do client side
> filtering after loading, we might end-up with lower number of records than
> loaded. Tables must be able to inform loader to load more more records.
