What should I do in matchmaking to add many players to a minimum number of rooms?

strix-support

Instead of letting players to choose rooms to join, I plan to let players join a room of large capacity as they come and to create another room when it becomes full. I want to perform the matchmaking so that many players join a minimum possible number of rooms. How can I achieve it?

Please consider the following when creating a script to join a room:

Choose a room with more members (memberCount) than other rooms. When calling SearchRoom, you can request sorting by a descending order of the number of members, which is suitable for the scenario.
A room with some vacancy at the time you searched may be occupied by other clients and you may fail to join it. If it happened and if you create a new room immediately, it is possible that too many rooms are created and the average number of members per room may be lower. So, you should retry joining an existing room several times. Also, setting the system’s upper limit (capacity) slightly larger and searching by a condition like memberCount < capacity - mergin rather than memberCount < capacity will reduce the frequency of errors caused by the occupied room.
