Project mention: A High-Performance, Java-Based Orchestration Platform | /r/java | 2023-10-11

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: Ask HN: Does async/await exist for transient processes? | news.ycombinator.com | 2023-08-30

See https://www.jbpm.org/ for one approach to the problem of long-running workflows which is based on the standard

http://www.omg.org/bpmplus/

which is not quite the programming model you want but it is similarly breaking up "functions" into small bits and serializing the state so that this can happen over long terms.

What you want has been done on an experimental basis, but maybe not industrialized, see

Project mention: Show HN: Workflow Orchestrator in Golang | news.ycombinator.com | 2024-03-04

Nice. It is great to see native lightweight opensource (I hope it is considering that someone said that there is no license file yet) solutions hit this space. For what it's worth, I have built something similar to this but for Java programming language. You can find it here -> https://github.com/americanexpress/unify-flowret. My reason for building something like this was that the product market is just too unwieldy to work with and has multiple layers of complexity which most of the time can be done away with. Just my opinion.

On a side note, you will at some point in time have to deal with multi version workflows. I know that this is one feature that limits wide adoption of an orchestrator.
