When should I use Apache Airflow instead of Kedro?

Scheduling and orchestrating complex DAG-based data pipelines at scale with a mature ecosystem. Teams needing hundreds of pre-built provider integrations for databases, clouds, and SaaS tools. Monitoring, alerting, and auditing pipeline runs via a rich web UI with full task history

When should I use Kedro instead of Apache Airflow?

Structuring and standardizing ML and data science projects for reproducibility and production readiness. Teams who want a framework to enforce modularity, data catalog management, and pipeline documentation. Transitioning notebook-based experiments into maintainable, testable Python pipeline code

What are the main weaknesses of Apache Airflow?

DAGs defined in Python can become hard to maintain and test in large codebases. Dynamic DAGs and parameterized runs are complex to implement correctly without anti-patterns. Resource-heavy deployment requires a database, scheduler, and workers to run at minimum

What are the main weaknesses of Kedro?

Opinionated project structure feels rigid for simple use cases or small scripts. Not a scheduler — needs Airflow, Prefect, or a similar tool to run pipelines on a schedule. Node, pipeline, and catalog abstraction has a learning curve that can slow initial productivity

How Python Data Engineers Use These Tools

Apache Airflow

Python data engineers define pipelines as Directed Acyclic Graphs (DAGs) using Airflow's Python SDK. DAGs are written as .py files that instantiate Operators — PythonOperator for custom logic, BashOperator for shell commands, and provider-specific operators for Postgres, S3, BigQuery, and Snowflake. Airflow is the industry-standard orchestrator for scheduling ETL jobs, managing dependencies between tasks, and handling retries in production data pipelines.

Kedro

Data engineering teams use Kedro to structure ML and analytics pipelines as modular, testable Python functions. The DataCatalog allows engineers to define data sources (S3 Parquet files, SQL tables, local CSVs) in a YAML config — switching environments just changes the catalog config, not the pipeline code. Nodes are pure Python functions that are easy to unit test.
