🎯 Use Cases

Deploying ML training pipelines on Kubernetes via Argo Workflows Migrating existing Airflow workflows to Tekton Pipelines Running hybrid workflows across multiple orchestration platforms Standardizing workflow definitions across teams using different engines

⚖️ Pros & Cons

✅ Pros

Engine-agnostic workflow definitions reduce vendor lock-in
Python-native interface lowers learning curve
Active open-source community with multiple engine integrations

❌ Cons

Limited to supported workflow engines (no custom engine support)
Potential performance overhead from abstraction layer
Dependent on underlying engines for advanced features

Overview

Couler provides a unified Python-based interface for defining and managing machine learning workflows across multiple workflow engines like Argo Workflows, Tekton Pipelines, and Apache Airflow. It simplifies workflow orchestration by abstracting engine-specific details, enabling users to write workflows once and deploy them on different platforms.

Problem It Solves

It eliminates the need to learn and maintain multiple workflow engine APIs, reducing complexity and increasing portability of machine learning pipelines.

Target Audience: Developers and teams working with data pipeline automation.
