How much data will we have to store?


Q: How much data would we have to store?


1 byte for timestamp and 1 byte for userId seems a bit low


Agree with you. 1 byte userID cannot cover daily posting users.


Agreed. 1 byte can only represents 256 users.


Why 2 bytes for 2 favorites? What data is stored here? UserId should be more than 2bytes right?
