You could this https://github.com/robfig/cron

This will print "Valid cron expression: */20 * * * *" to the console. You can find more information about this library, including installation instructions, on its GitHub page: https://github.com/robfig/cron

I used robfig/cron on each of the workers. I only had on the order of ~10 workers so polling was not an issue.

There are many excellent open-source projects on GitHub, where the code is transparent and available to everyone. As software developer, we can learn a lot from them including software engineering, unit testing, coding style standardization, etc. We can even find issues by looking into their code, and submit pull requests to contribute to tech communities. Today we are going to dig into the source code of a popular Golang open-source project on GitHub, robfig/cron, which is small and with clear annotations, and is very suitable for new developers to learn how to read and analyze source code.

Now let's implement the core of task scheduler, cron job. We will be using robfig/cron, a reputable cron library written in Go.

# Hello Everyone! Ive built this cronjob library after the trusted: https://github.com/robfig/cron.

I suggest this library.

You can take inspiration on cron lib, create a Job i's a function that you give a channel for quit action, and a probably cancel function (from background.WithCancel) for cancel running asynchronous task. You can have a scheduling worker if you decouple a great task to multiple job that listen to a channel that emit event.

Contributing to Apache Airflow's open-source project immersed me in collaborative coding. Experienced maintainers rigorously reviewed my contributions, providing constructive feedback. This ongoing dialogue refined the codebase and honed my understanding of best practices.

In week Two, I contributed to the Apache Airflow repository.

Apache Airflow is an open-source platform to programmatically author, schedule, and monitor workflows. The platform features a web-based user interface and a command-line interface for managing and triggering workflows.

Airflow is the most widely used and well-known tool for orchestrating data workflows. It allows for efficient pipeline construction, scheduling, and monitoring.

AIRFLOW This is more of a library in my opinion, but Airflow has become an essential tool for scheduling in my work. All our ML training pipelines are ordered and scheduled with Airflow and it works seamlessly. The dashboard provided is also fantastic!

I agree there are many options in this space. Two others to consider:

- https://airflow.apache.org/

- https://github.com/spotify/luigi

There are also many Kubernetes based options out there. For the specific use case you specified, you might even consider a plain old Makefile and incrond if you expect these all to run on a single host and be triggered by a new file showing up in a directory…

You can try and contribute some new connectors/operators for workflow managers like Airflow or Airbyte
