How to send in-app notifications to all users in my server?

Need all users to send game messages from developer

@Raja_Nukala This can be a costly operation to perform because with games that have millions of players would require the entire dataset of user IDs to be pulled into memory to be processed for in-app notifications. The alternative is to use a batch-orientated API to send out the message to players in groups of 1000s of user IDs.

Do you have some example use cases for the type of messages you’d like to broadcast to all players in the game?
