 Apache Hamilton (incubating) is a lightweight Python library for directed acyclic graphs (DAGs) of data transformations. Your DAG is **portable**; it runs anywhere Python runs, whether it's a script, notebook, Airflow pipeline, FastAPI server, etc. Your DAG is **expressive**; Apache Hamilton has extensive features to define and modify the execution of a DAG (e.g., data validation, experiment tracking, remote execution).
 
 To create a DAG, write regular Python functions that specify their dependencies with their parameters. As shown below, it results in readable code that can always be visualized. Apache Hamilton loads that definition and automatically builds the DAG for you!

 Here you'll find documentation about the sf-hamilton-contrib package that curates a collection of Apache Hamilton Dataflows that are
 ready to be used in your own projects. They are user-contributed and maintained, with
 the goal of making it easier for you to get started with Apache Hamilton.

 This is an implementation of the [Language Server Protocol](https://microsoft.github.io/language-server-protocol/) to provide a rich IDE experience when creating Apache Hamilton dataflows.
 
 It currently powers the Apache Hamilton VSCode extension and could be integrated into other IDEs.
