This question is in regards to a discussion that went on here.
I have a collection of urls in an array that I need to parse through using a Firebase Cloud Function. Instead of iterating through the URL's on the client (I could potentially have hundreds of items in this array) and making individual requests to the function, I'd rather store the entire array in Firestore, pass the ID of the collection to the function, grab the array on the server, iterate through it and perform some operations, and then either save it back to Firestore with a new ID and respond back to the client with that ID so it can consume/destroy, or just respond with an newly mutated array (not sure which one I'd like to use yet).
There doesn't seem to be a "preferred" way to store arrays with Firebase since it's generally considered evil, however, what if I don't plan to keep the data around for very long?
