I can read in Microsoft's documentation that certain characters are restricted form the resource id, but I can't find any similar documentation for the partition key. As of now, I have "/" in the name of my partition keys, but I'm a bit worried what could happen if the partition key is subject to the same restrictions as the id. Do anyone know if there are any restrictions to the partition key?
