When someone is in the livekit room, and refreshes his page, does that count as the participant has disconnected from the room? would the @room.on("participant_disconnected") be triggered?

Thanks for reaching out, Mok. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

when the participant ends the interview, would this @room.on("participant_disconnected") also be triggered? the callback for the session end would also be triggered right? Could there be race conditions if they both update the db state?

Yes, the

@room.on("participant_disconnected")

event is indeed triggered when a participant ends their session. I understand how having a separate callback for the session end that also updates the database might feel a bit tricky, especially since there’s a chance for race conditions if both callbacks try to update the same state at the same time. To help you avoid those race conditions, here are a few friendly suggestions: • Try using database-level constraints or transactions to make sure your updates happen safely and atomically. • If you’re working with shared in-memory state, implementing application-level locking can really help keep things in order. • Designing your database updates to be idempotent is a great practice, especially when multiple callbacks or retries might occur. • And if you’re dealing with distributed systems, using message queues or event sourcing can help serialize event processing across different instances smoothly. If you’d like, I’m here to walk you through any of these strategies or answer any questions you have. Just let me know!
