Problem

We run a livestream platform where creators go live and viewers drop in and out, fire off chat, and send paid virtual gifts that fund creator payouts. The same broadcast produces viewer visits, chat, and gift purchases at wildly different volumes, and every past gift must keep paying out the exact dollar amount it was worth the moment it was sent, even after finance reprices the gift catalog. Design the data model behind payouts, content recommendations, and engagement analytics.

Summary

Someone goes live, thousands tune in, chat explodes, and virtual gifts start flying.
