A modern programming language that makes developers happier.

kotlinlang

i’m a coroutine newbie
and i’m stuck integrating co-routines and `CompletionStage`
overall, my goal is to check whether i’ve an entity in the cache
and if it’s not, go to the database
the cache-checking returns a `CompletionStage`
and the database repo is a suspending function
how can i combine the two?
the best i can do is:
```val person = cache.getAsync(id).await()
return if (person == null) repository.findById(id)
else person```
and obviously, it’s not the right way to do it
i don’t find the correct operator
help greatly appreciated :slightly_smiling_face:

Seems fine. I'd just clean up the Kotlin.
```return cache.getAsync(id).await() ?: repository.findById(id)```
