How do you deal with getting updates of feature flags in Cloud Functions (e.g. AWS lambda).
• Just fetching the features on every feature check?
• Using the webhook is not an option in this scenario because the lambda function/docker container is behind a load balancer 🤔 is that correct or do i have a mistake in my understanding?

Hi Valentin. There are a few ways to do it.
1. Fetch the features in your lambda outside of the event handler (so they are shared between invocations). Add logic to re-fetch if more than X seconds old.
2. Add a webhook that persists the feature JSON in something like Redis or DynamoDB. Read from there in your functions.
