I have a suggestion: In the approach of keeping track of who all have read a message in a chat group, instead of storing the IDs initially and removing them (which is a costlier approach), we can just implement a counter (i.e the no.of users of a group) and go on decrementing the value towards zero. A single time calculation of number of users for setting the counter will happen at the initial, but helps memory wise. I think this would improve the efficiency.

then you won't know which user in the groupchat has already seen the photo.

If we simply have a pointer, although it is memory efficient, we do not have a track of who's actually have not seen it. Which will be another problem in case of new members added and old members are removed

Keerti, I started watching your videos for Adv Software engg course during my masters to understand SOLID and Design patterns. Since then, I have been following your channel. Completed watching this video and I must say you are an inspiration to me, you always ask the right questions. I hope to become like you! 🤞

How will the triggering part of the group delete happen ? Like we are removing from the set as users are reading the messages but when the set will become empty how will we know ? Will there be a cron who checks this say after every 15 mins ?

I have few questions 1. Can't mobile app send 1 read receipt for each message when everyone reads it since, app will have latest copy of current users in group ? 2. Cant we build group messages as consumer publisher design ....all group user can subscribe to group and poll message or push mechanisms can also be build for user to view messages ? Group service can own this central message broker which keeps cache of all connected uses in group Thanks in advance

How the triggering part will happen for group delete? Like I am removing from the set as people are reading it, but when set will become empty how the group delete API will trigger? Will it be through cron who checks if set is empty after say every 15mins?
