Some of the main usage scenarios for keyless entity types are: Serving as the return type for SQL queries. HINT: A lot of factors might affect the benchmark time such as index, column type, latency, throttling, etc. The other one is Include lambda method. These can be used to set predefined filter on entities that are to be included. In this tutorial, we look at include method, and learn how to load entities from multiple. Usage scenarios.
