LINE OpenChat is a chat service that allows LINE users to chat with other users that have similar interests without having to add them as LINE friends.
Due to how OpenChat can have thousands of users sending and receiving messages in real time in a single OpenChat room, it can create "hot chats" that instantly spikes traffic 100 times more than usual, putting a heavy load on the OpenChat server in a short amount of time.
In this session, Injae will introduce architecture improvements and the various methods used to handle rapidly changing traffic on the OpenChat server, such as circuit breakers, throttling, and debouncing among others.
