Example of caching using aiocache package. To run it you will need a Redis
|
|
instance running in localhost:6379. You can also try with SimpleMemoryCache.
|
|
|
|
Running this example you will see that the first call lasts 3 seconds and
|
|
the rest are instant because the value is retrieved from the Redis.
|
|
|
|
If you want more info about the package check
