Firebase中单个主题订阅的用户最大限制是多少? [英] What is the maximum limit of users for single topic subscription in Firebase?

问题描述

我正在使用Firebase主题发送通知.与此同时，我遇到了Firebase通知控制台，该控制台在选择通过主题发送通知时显示(topic-name)<1000 estimated user

我已经阅读了 POST .它说可以创建无限个主题.但是我的问题是，可以订阅一个主题的用户数上限是多少，因为在控制台中显示(topic-name)<1000 estimated user，并且Firebase在文档中没有描述关于最大限制用户订阅单个主题的任何内容. /p>

如果单个主题订阅的用户限制为1000个，而不是应用程序激发该用户限制时会发生什么.它会向前1000个用户发送通知吗，根本不会发送通知?

解决方案

我找不到适合您的答案链接.但是在2015年，GCM限制了100万个用户订阅单个主题，但他们已经取消了此限制. FCM将GCM用作核心，这意味着用户订阅任何主题都不受限制.

我们现在很高兴地宣布，我们将为您的应用程序提供无限的免费主题.这意味着应用程序开发人员可以在每个主题中放置不限数量的设备，并创建不限数量的主题.

第二个问题显然告诉您，fcm估计不到1000个用户订阅该主题.这并不意味着您无法发送到1000多个设备.您误解了<估计有1000位用户.

I am using Firebase topics to send notification.While doing so i came across the Firebase notification console which shows (topic-name)<1000 estimated user on selecting sending notification through topics

I have read this POST.It says Firebase can create unlimited topics.But my question is that how many maximum number of user can subscribe to a single topic because in console it showing (topic-name)<1000 estimated user and Firebase has not describe anything in doc about max limit users subscription to an individual topic.

If it has the limit of 1000 user to a single a topic subscription than what will happen when app excited this user limit.will it sent notification to first 1000 users of it will not send notification at all?

解决方案

I can't found the answer link for you.But at 2015 GCM limit 1 million user to single topic subscription but which they already remove this limitation. FCM is using GCM as it core so which mean it is unlimited for user subscription to any topic.

You might get some point form this link

We’re now happy to announce that we’re allowing unlimited free topics for your app. This means app developers can place an unlimited number of devices within each topic and create an unlimited number of topics.

By your second question that obviously told you that fcm estimated lesser than 1000 user subscribe to that topic. It's doesn't mean you cannot send to over 1000 device. You have misunderstading the meaning of < 1000 estimated users.
