I have a Flutter app with a Firebase Firestore database.
I want to integrate my app with Google Calendar, and I need the app to have real-time access to the calendar data.
Moreover, my app needs to manage some data associated to each calendar event that is app-specific and goes beyond the scope of Google Calendar itself.
So I need to store this additional information somehow in the Firestore database.
In summary, the app needs to be ab..

Let’s say I have 100 million users in the database, and each of them have a reward point associated with it. This reward point is eventually consistent. And we need to rank the users based on this reward point. Now, I know how to find top N users who are having most reward points. Basically, we may have a separate datastore to store top N users at any given point. I can use a heap to keep track of top N at any given point and flush it to the DB. But, what if I need to find the rank of a random user (also users who are adjacently ranked to the given user) from 100 million users? We can’t put all 100 million users into memory for sorting. So, how do we achiev..

I am playing around with a cross-language spell-check sort of thing, and am still in the prototyping/ideation phases. Basically I have thought of something like a Trie data structure, but I keep wanting to “reuse” parts of the trie, but can’t figure out if it’s possible. Wondering if you can just tell me if it’s possible to do a Trie DAG sort of thing or not, and if not, wh..
