Project mention: Building in Public: Leveraging Tublian's AI Copilot for My Open Source Contributions | dev.to | 2024-02-12Contributing 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.
Project mention: Prioritizing Concurrent Requests: Queuing system to handle distributed processes and messages with NodeJS and Bull | dev.to | 2024-03-15To implement the solution with a queue, I used a package called 'Bull' (https://github.com/OptimalBits/bull). It's a library that helps with distributed job control, providing some very useful solutions for this type of work, such as background job processing, queues with priorities (FIFO, LIFO, and others), among other features. 'Bull' uses Redis for queue storage, so if your application crashes for any reason, once it's back online, it will continue executing the processes that are in the queue. In our case, we'll use the FIFO (First in, first out) queue solution, meaning priority based on arrival order.
While many ways to write scalable Node.js applications exist, all narrow down to the underlying architecture. However, common hurdles in Node.js include serving static files, task scheduling, and utilizing available resources. To combat these, you can use a tactical approach. Because serving static assets with Node.js takes CPU time, a proxy content delivery network like CloudFront should help fix it. Recurring tasks need to fire events, which isn’t reliable with setTimeout or setInterval. As a solution, you can use a task scheduler framework like agenda.js. To handle resource utilization, you can use the cluster feature in Node.js, which listens to ports, accepts new connections, and distributes them across workers with built-in smarts to avoid overloading the process.

Kestra's communication is asynchronous and based on a queuing mechanism. It leverages the Micronaut framework and offers two runners: one that uses a database (JDBC) for both the message queue and resource storage, and another that uses Kafka as the message queue and Elasticsearch as the resource storage. The platform is fully extensible and plugin-based, providing a rich set of plugins for various workflow tasks, triggers, and data storage options. For those interested, the GitHub repository is available here: https://github.com/kestra-io/kestra
Project mention: JobRunr: A library for background processing in Java | news.ycombinator.com | 2023-05-25Looks like it's abandoned fork and the current development is at https://github.com/go-co-op/gocron

I found this one, but I don't know what it's worth it? easyappointments.org ( feel free to remove if it breaks the community guidelines )
We’ve used this [1] library before and were able to customize it pretty heavily.

If you only need a single instance, you can use Bree to handle your cron jobs without blocking your main thread.
[Postgres Extensions] pg_cron 1.5.2 (new projects only) now supports sub-minute schedules. PR
In addition, here's a good project for you to look at for cron (Crontab) type functionality you might want to borrow from: https://github.com/quantum-elixir/quantum-core
