Send message to multiple devices

[KoblStone]

I want to send notifications to specific users using tokens. firebase-admin can't send multiple tokens so I'm using:

for obj in queryset:
            token = obj.app_token
            message = messaging.Message(android=android_config, data=data, token=token)
            try:
                messaging.send(message=message, dry_run=False, app=default_app)
            except Exception as ex:
                print('Error %s' % ex)

But it seems that "FCM" is blocked due to the fact that I send a lot of requests per second. Because after that I can not get a notification for a while.
Can this be solved?

Hey there! I couldn't figure out what this issue is about, so I've labeled it for a human to triage. Hang tight.

Hmmm this issue does not seem to follow the issue template. Make sure you provide all the required information.

I believe there's some on going work to support multicast messaging in the new FCM REST API. This will be supported once that is implemented (although I don't know what the exact timeline is).

In the meantime, can you use topic messaging to implement your use case?

No. The list is generated dynamically and I will need to create multiple topics

Update: as mentioned in firebase/firebase-admin-node#315, we are working on a new batch-send API for Admin SDK.
