Firstly i can’t tell the details of my project but i can explain it with different situation. Let’s say we have a 1000×1000 canvas. So theres 1,000,000 rows of data that will in sync real-time. So firstly i need to chose a database for that and i want to run it serverless. I think firebase db is ideal for that but you can make suggestions to me. Now there’s a big problem on budget. I can’t fetch the all of the 1 million rows at the every change i need to fetch just changed row. Thanks for your attention. I need help on that.

Idk i maybe i use datechanged parameter to it so i can fetch all of the data at the beginning and continuisly fetching data that datechanged > beginningdate.
