Channel API in AppScale - Raj's Blog (nlake44): "Google's newest API is the Channel API which allows for the pushing of messages to a client's javascript code. This blog entry explains AppScale's scalable implementation which is built using ejabberd and strophejs.
There are two sets of APIs for the developer. First is the python API which consists of create_channel(app_client_id) and send_message(app_client_id, message). The create channel API under the covers uses the xmpp service implementation of AppScale. We are able to leverage ejabberd to take care of the distribution and sending of messages for us. The trick here lies in that we must create temporary accounts with each new channel created. This requires garbage collection of channels which live on longer than a prescribe period of time. "
