<span id="Overview'>Overview
A chat room is an online virtual channel that provides a venue for communities of users with loose membership control. Users can join or leave a chat room freely. In general, a chat room has no fixed membership organizational structure. Typical scenarios are the chat rooms in live streaming. The chat room is a paid extension capability that are available after you upgrade from IM Basic to IM Pro.
How can you choose between chat rooms and group chat features?
First, no upper limit is applied to the number of participants in chat rooms and groups can only support 200 people by default. You can expand the capacity of groups. If a large number of people chat in your scenarios, use chat rooms.
However, it is not suitable for group chat scenarios with a small number of people. For example, in chess and card games, only 4 players communicate with each other, chat rooms are appropriate. Because chess and card rooms are temporary sessions, players may leave or join the session at any time. You cannot handle disconnection under abnormal conditions for groups.
A chat room is analogous to a square. As long as users have access to the portal to the square, anyone can join or leave the chat room at any time. The group is similar with a company. The company is a more private organization. Only members of this organization can join. To become a member, you can request to join a group or be invited to join a group.
IM chat room uses multi-layer architecture design that can handle large-scale chat rooms with an unlimited number of participants,and can meet the real-time requirements of messaging.
