how exactly does the livelinks work

like how does it know to listen constantly for updates

how does it query the database that quickly

oh is that how lambda and dynamodb work together?

yeah it uses dynamodb streaming to trigger a lambda whenever the posts or threads table gets fucked with and then that sends the appropriate messages to ppl
the lambda gets sent the old and new value so its quick

theres a little bit more going on but ya thats the idea

ugh calculus
