Channel Groups API for PubNub Python-Asyncio SDK

Channel Groups allows PubNub developers to bundle thousands of channels into a group that can be identified by name. These Channel Groups can then be subscribed to, receiving data from the many back-end channels the channel group contains.

Channel Group operations

You can't publish to a Channel Group. You can only subscribe to it. To publish within Channel Group, you need to publish to each channel individually.
