The `channelConfigurationOptions` folder contains JSON files describing channels advanced configuration.
Filenames are like `1.json` where `1` is the channel id.
The content of the files are similar to the content sent by the front-end when saving these configuration.
## channel2room and room2channel
Some parts of the plugin need a quick way to get the channel id from the room id, or the all room id from a channel id.
We won't use SQL queries, because we only want such information for video that have a chatroom.
So we have 2 folders: `channel2room` and `room2channel`.
When a chatroom is created, we create 2 empty files:
* `channel2room/channel_id/room_id@muc_domain`
* `room2channel/room_id@muc_domain/channel_id`
Where:
* `muc_domain` is the room's domain (should be `room.your_instance.tld`)
* `channel_id` is the channel numerical id
* `room_id` is the local part of the room JID
So we can easily list all rooms for a given channel id, just by listing files in `channel2room`.
Or get the channel id for a room JID (Jabber ID).
Note: we include muc_domain, in case the instance domain changes. In such case, existing rooms
could get lost, and we want a way to ignore them to avoid gettings errors.
Note: there could be some inconsistencies, when video or rooms are deleted.
The code must take this into account, and always double check room or channel existence.
There will be some cleaning batch, to delete deprecated files.
