Video Conferencing with Postgres

Possible optimization: instead of sending full JPEG frames, send information about what’s changed since the last frame, like an MPEG stream

The logical next step is to implement change data capture and time travel with Kafka.

It is an amazing testament to technology that we can do smooth-ish live video transmission with full acid compliance at very low costs. I am not that old but old enough to remember when YouTube used to constant buffer.

This is just a demo as the author stated. Video conferencing should use UDP and allow loose of data in exchange of low latency. That's not the case for logical replication.
