How to Communicate Between Storyline and a mySQL Database

Nice post Nathaniel. Quite complete. I use Firebase/firestore as that allows me to get realtime data and thus make multiplayer games. Probably somewhere this year i am switching to Azure Cosmos as this is fully compliant with our Universities security rules. I am not sure yet whether Cosmos gives the same flexibility as Firestore though. As your post triggered me to search whether Azure Cosmos has similar features as Firestore on realtime updates i found this article, thus it feels this will be possible.
