Hi, I am trying to implement an async function that looks up a value in a cache or, if the value doesn't exist in the cache, queries a web service, but I'm having trouble creating the cache. I've tried to create a RichAsyncFunction and add a map state as cache, but I'm getting: State is not supported in rich async functions.
What is the best practice for doing this? I guess I could have a previous step with state and send the responses from the rich function back as an iteration, but I would guess that's the wrong approach... Thanks, William
