How to make a subscribe users for the group vk api?

Good afternoon. In General, there is a database with the users who wrote messages in the community. You need to make the function in node js that will send them my message. I thought to go through the while loop, but users in the mysql Database a lot. It turns out the program just hangs or just long runs. Maybe you can somehow query mysql to record all of the user IDs in an array and send again?
