awehflow

coverage report pipeline status

awehflow is a configuration-driven framework for Apache Airflow that dynamically generates DAGs from simple HOCON or YAML files. It comes with built-in metrics, logging, and alerting to streamline your data orchestration.

Core Concepts

  • Configuration-Driven: Define complex DAGs using a clear, hierarchical configuration. No need to write repetitive Python code for each pipeline.
  • Dynamic DAG Generation: awehflow automatically constructs and orchestrates Airflow DAGs based on your configurations.
  • Built-in Observability: Comes with out-of-the-box event handlers for persisting metrics to a database and alerters for notifications on pipeline status.
  • Extensible: Easily add your own custom event handlers and alerters to integrate with any service.

Getting Started

Configuration Reference

Custom Operators and Sensors

awehflow includes a collection of custom operators and sensors to extend Airflow's functionality. While these custom operators provide specialized capabilities, awehflow is fully compatible with all standard Airflow operators. You can use any operator available in your Airflow environment by referencing its fully qualified class name in your configuration.

Command-Line Interface (CLI)

awehflow includes a CLI for generating and validating configurations.

Advanced Features

Event Handlers & Alerters

awehflow has a built-in event system that allows you to run custom code in response to pipeline events. Alerters are a special type of event handler designed for sending notifications.

Troubleshooting

For Developers

Development Environment Setup

To contribute to awehflow, follow these steps to set up a development environment for a specific Airflow version.

  1. Install Miniconda: Follow the official instructions.
  2. Create Conda Environment (x86 on Mac ARM): If you are on an ARM-based Mac, create an x86-emulated environment. Add this function to your `.zsh
