 | ⚠ IMPORTANT |
 | :- |
 | Entity scene and section loading is always asynchronous, and there is no guarantee of how long it will take for the data to be loaded after the request. In most cases, code should check for the presence or absence of specific data loaded from scenes rather than check the loading status of the scenes themselves. This approach avoids tethering code to particular scenes: if the data is moved to a different scene, downloaded from the network, or procedurally generated, the code will still work without modification. |

 You can offload the processing of entity data to worker threads with the [C# Job System](https://docs.unity3d.com/Manual/JobSystem.html). The Entities package has two interfaces for defining jobs that access entities:
 
 - [`IJobChunk`](https://docs.unity3d.com/Packages/com.unity.entities@latest?subfolder=/api/Unity.Entities.IJobChunk.html), whose `Execute()` method is called once for each individual chunk matching the query.
