# Async Data Factory
|
|
|
|
This is an example demonstrating the construction of async state with `App::data_factory`.
|
|
|
|
## Reason:
|
|
|
|
Use of a `data_factory` would make sense in these situations:
|
|
|
|
- When async state does not necessarily have to be shared between workers/threads.
|
|
- When an async state would spawn tasks. If state was centralized there could be a possibility the tasks get an unbalanced distribution on the workers/threads.
|
|
|
|
## Context
|
|
|
|
The real world difference can be vary by the work you are doing but in general it's a good idea to spread your similarly-expensive async tasks evenly between threads and have as little cross threads synchronization as possible.
