google app engine - Can GCM cloud server access my app server database table? -


i using google cloud messaging in web based android application. want send message of android apps through gcm (one one, not simultaneously). commonly, web server sends request gcm data , gcm sends data particular app. if database contains records of 10 apps web server request gcm 10 times. there way web server gives access of database table gcm. gcm using database table send messages apps 1 one. web server not need request gcm server 10 times. possible? in advance kind reply!

there no way google can access database, can send multicast messages 1000 recipients using registration_ids parameter instead of to in http request.
