landlord VS windmill

on the java stuff - why not something like graalvm or https://github.com/landlord/landlord ?

GitHub: https://github.com/windmill-labs/windmill

We use https://windmill.dev which is great for this!

Founder of https://windmill.dev here which share many similarities with Maestro.

> Maestro is a general-purpose, horizontally scalable workflow orchestrator designed to manage large-scale workflows such as data pipelines and machine learning model training pipelines. It oversees the entire lifecycle of a workflow, from start to finish, including retries, queuing, task distribution to compute engines, etc.. Users can package their business logic in various formats such as Docker images, notebooks, bash script, SQL, Python, and more. Unlike traditional workflow orchestrators that only support Directed Acyclic Graphs (DAGs), Maestro supports both acyclic and cyclic workflows and also includes multiple reusable patterns, including foreach loops, subworkflow, and conditional branch, etc.

You could replace Maestro with Windmill here and it would be precisely correct. Their rollup is what we call the openflow state.

Main differences I see

Data Handling: Utilizes Windmill for data pipelines, with a primary database powered by PostgreSQL. Auxiliary data storage is handled by MongoDB, with Redis for caching to optimize performance

Look very similar to the script builder portion of https://github.com/windmill-labs/windmill, but not open-source, not self-hostable, and without open-source integrations (https://hub.windmill.dev/)

disclaimer: I'm founder of ^

If you need a job queue on Postgres, https://windmill.dev provide an all-integrated developer platform with a Pg queue at its core that support jobs defined in python/typescript/sql

windmill.dev - Windmill is an open-source developer platform to quickly build production-grade multi-step automation and internal apps from minimal Python and Typescript scripts. As a free user, you can create and be a member of at most three non-premium workspaces.
