I am implementing a Google App Engine app for which I need to create channels at a high rate. To avoid incurring excessive costs owing to the relatively stingy quota for channels, I am going to use the approach of channel pooling
Since in this model, channels will be reused by future clients, I would like them to be as long lived as possible - up to 24 hours, which is the time after which quotas reset and extending a channel is no longer profitable. This seems straightforward:
token = create_channel(clid, duration_minutes=1440)
...but I would like to know if the duration_minutes argument has an upper limit. Does anyone know what it is?
