I need a job scheduler (a library) that queries a db every 5 minutes and, based on time, triggers events which have expired and rerun on failure.

It should be in Python or PHP.

I researched and came up with Advanced Python Scheduler but it 开发者_JS百科is not appropriate because it only schedules the jobs in its job store. Instead, I want that it takes jobs from a database.

I also found Taskforest, which exactly fits my needs except it is a text-file based scheduler meaning the jobs have to be added to the text-file either through the scheduler or manually, which I don't want to do.

Could anyone suggest me something useful?

Here's a possible solution - a script, either in php or python performing your database tasks - a scheduler : Cron for linux, or the windows task scheduler ; where you set the frequency of your jobs. I'm using this solution for multiple projects.

Very easy to set up.

Celery runs best using RabbitMQ, but also has support for databases, using SQLAlchemy.
