Is there any limit to send push notification for users already registered one topic ? I sow an limit ( users < 1000 ) in the google fb console when I tried to send a push notification. Any idea?
AFAIK there is no limit. The 1000 is for the users which can be reached at once. If you are over that firebase will need some more time to send to everyone.

Yes. Sending 1.000.000 messages will take some time. Let's assume it will take 0.5s per message. So you are able to send 2 per sec/120 per minute/7200 per hour and 172.800 per day. To reach 1.000.000 you need 5.8 days (maybe Google is faster to do it).
More important: Why do you want to send the same message to so many devices?
If somebody has an app with 1.000.000 users and wants to send a push message ( like an updating notice or something like this ) it will take 5 days to all of them receive this notice !?
Edit : each message takes about 50milisecond ( 0.05 a second ) or faster. For 1.000.000 users it will takes about 14 hours ( 1.000.000 /( 3600 sec * 20 message )=~ 13.88888 hours
