howto send notification to multiple devices (over 5000 devices)? (Python firebase admin sdk have limit of 100 devices)

[Subin Joseph]

Hi,

I am using firbase sdk to implement web push notification.Here is my idea. 

The registraiton token and language prefence of the client will be stored in the server side ( in my sql server).

In order to send notification, we retrieve registration token list from databse and loop through first 100 tokens each tiime and send notification. 

I used the following link for the reference. 

https://firebase.google.com/docs/cloud-messaging/send-message#send-messages-to-multiple-devices

But I have read that, when we send multiple request within short period of time ( within one sec), there are chances of some requests getting rejected. We hope that, there will be  50000 

How can I successfully send notification to mutltiple devices over 100 devices?Is it possible to increase the limit ?

Thanks
Subin

Python SDK can send up to 500 messages in a single batch. You should be able to easily reach 5K devices with that. If that's too slow you can also look into topic messaging.

Hi Hiranya,

Thanks a lot for your reply. 
Latency is not a big issue. But suppose the number of subscription is increased to very large number (eg: 50K subscriptions), is there  chance of some notification requests getting rejected while sending the notification as many batches of 500 in short period of time ( within one sec)? 

Thanks and Regards
