## Usage:
|
|
This is an example on constructing async state with `App::data_factory`
|
|
|
|
## Reason:
|
|
`data_factory` would make sense in these situations:
|
|
- When async state not necessarily have to be shared between workers/threads.
|
|
|
|
- When async state would spawn tasks on `actix-rt`. If we centralized the state there could be a possibility the tasks get a very unbalanced distribution on the workers/threads
|
|
(`actix-rt` would spawn tasks on local thread whenever it's called)
|
|
|
|
## Requirement:
|
|
- `rustc 1.43 stable`
|
|
- `redis` server listen on `127.0.0.1:6379`(or use `REDIS_URL` env argument when starting the example)
|
|
|
|
## Endpoints:
|
|
- use a work load generator(e.g wrk) to benchmark the end points:
|
|
|
|
http://127.0.0.1:8080/pool prebuilt shared redis pool
|
|
http://127.0.0.1:8080/pool2 data_factory redis pool
|
|
|
|
## 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 *identical* async tasks evenly between threads and have as little cross threads synchronization as possible.
