When I use API Gateway, I can find the limits from this link: https://docs.aws.amazon.com/apigateway/latest/developerguide/limits.html
One of the big limits for websocket is 2 hours duration time. Because of that, I am going to use App sync with websocket connection but I can't find any limits on that. Does AWS release any limits for AppSync?
The service quotas for AppSync can be found in the link.
