推荐答案
主题或订阅的数量没有限制.最初启动主题后的第一年，订阅人数限制为100万，但该限制已在今年(2016年)的Google I/O中取消. FCM现在支持每个应用程序无限的主题和订阅者.请参见文档以确认.
There is no limitation on the number of topics or subscriptions. There was a limitation of 1 million subscriptions for the first year after topics was initially launched but that restriction was removed at this year's (2016) Google I/O. FCM now supports unlimited topics and subscribers per app. See the docs for confirmation.
