在Bull队列和数据库触发器之间选择

Question

I have a use case where I have to create a record in the database for users repeatedly on a scheduled basis. Let's say every Monday Weekly/BiWeekly. There are two ways with which i can achieve it.

1. Using Database Triggers to Create a record on the time. But I don't know how to repeat it. I have to create a trigger for the next schedule when this trigger runs, which i don't think is right approach.

2. Using Queues to handle the scheduling and executing the repeated jobs. But adding a job for each user is not a good idea I guess. I might be wrong but there is no other way to achieve my goal.

I am confused on what to choose between the two. Let's say i have to do this for 1 million users every week Monday at 9.00 am

Which approach will scale?

I am using nodejs as my backend and using Bull-Queue for the queue and postgres as my Database.

Answer 1

Using Database Triggers to Create a record on the time. But I don't know how to repeat it. I have to create a trigger for the next schedule when this trigger runs, which i don't think is right approach. - Not a right approach based on the so many factors like - memory, number of requests and code quality.

So I went with the second approach:

Using Queues to handle the scheduling and executing the repeated jobs. But adding a job for each user is not a good idea I guess. I might be wrong but there is no other way to achieve my goal.
