Massive FCM message amounts. Best Practise?
Hey, if possible, I'd like to hear your opinion about this situation I've got in right now.I will simplify a little here, as the whole context doesn't really matter, so trust me, what I want to do makes 100% sense if you'd know the whole story.Basically at first launch the user can choose a main-topic, 1 out of 30 and after that, he can select sub-topics (options depending on the main-topic) out of a list.The twist is that sometimes a sub-topic can be selected via all main topics, so basically I'd need to account for the situation that all sub-topics could also be selected via all main-topics.And basically after the user has selected those, they'll get a daily notification about the topics via cloud functions and fcm.Now for the tricky part : I'm using fcm topics which the devices subscribe to, so I can basically broadcast those messages.At first I thought : Yeah, I'll just create a fcm topic for every main-topic and sub-topic there is, until I realized, I'd then be blasting out a massive amount of notifications.The information broadcasted per notification is not big at all, and although it sounds stupid, basically the content of every notification can be compressed to one digit.So basically, instead of broadcasting one message with one digit per topic, I'd want to publish one notification with all digits based on the selected topics on a daily basis to the user.The problem is that with all possible combinations to account for, I'd be sending in the millions of notifications per day, since I'd need to account for every possible combination of main-topics and sub-topics.Could you think of a better solution than just subbing a user to topic /topics/m12.s72.s63.s45.s52.s89.s31.s21.s94 and so forth since it doesn't seem exactly like best practise to me..?I'd be interested to hear your thoughts!​(BTW : I'm using as mentioned Firebase Cloud Messages fired by Firebase Cloud Functions to Flutter Applications running on Android and iOS)
