'trigger some event with message on specific time
How can I trigger some event at a specific time with some message?
Example: Someone scheduled a "Happy birthday" message on his friend's birthday at 12:00 am. So this birthday event should be triggered with a "Happy birthday" message on his birthday at 12:00 am.
The only solution I can come up with about how this work is a cron job that runs every min and checks the expired time and triggers that event.
But if we have a lot of events then querying every minute is not a good idea and it gives 1 minute error also.
So can we use any services like apache Kafka (but it does not schedule events at some specific time) to trigger events?
