CRON task every minute is it ok?

Question

linux

Hello, is it ok to create a task in CRON for every minute?
For example, I need to execute a certain php script every minute that checks the database.
And is it normal to do queries to the database every minute?

Answer 1

Not normal.
And if you need to run every half a minute, will you insert sleep?
What if the task lasts longer than a minute?
Apparently, you have chosen the wrong tool. Perhaps you need to do on some event, and not check the database. Think about queues.
We put the event in the queue - the queue handler processed it without delay.

Answer 2

No.
Write demon.
