Apache Hamilton (incubating) is a general-purpose framework to write dataflows using regular Python functions. At the core, each function defines a transformation and its parameters indicates its dependencies. Apache Hamilton automatically connects individual functions into a Directed Acyclic Graph (DAG) that can be executed, visualized, optimized, and reported on. Apache Hamilton also comes with a UI to visualize, catalog, and monitor your dataflows.

# GraphAdapters

This section helps determine ways to execute Apache Hamilton. Note that these are special cases of the [Lifecycle Adapters](/book/reader/apache-hamilton-incubating/lifecycle-hooks) meant to help with execution. They implement multiple lifecycle customizations in a single place.
