                    <h2>The Evolution of Python Data Pipeline Tools</h2>
                    <p>The Python data engineering ecosystem has matured significantly in 2026, with new tools emerging and established frameworks evolving to meet the demands of modern data infrastructure. As organisations handle increasingly complex data workflows, the choice of pipeline orchestration tools has become critical for scalability, maintainability, and operational efficiency.</p>
                    
                    <p>This article provides a head-to-head comparison of the leading Python data orchestration tools: Apache Airflow, Prefect, Dagster, and the rapidly growing Flyte. We'll analyse their core concepts, developer experience, multi-cloud support, and pricing to help you choose the right framework for your data engineering needs.</p>
                    <p>Key trends shaping the data pipeline landscape:</p>
                    <ul>
                        <li><strong>Cloud-Native Architecture:</strong> Tools designed specifically for cloud environments and containerised deployments</li>
                        <li><strong>Developer Experience:</strong> Focus on intuitive APIs, better debugging, and improved testing capabilities</li>

Dagster wins for asset-based thinking and strong local development. For most UK SMEs starting fresh, Prefect offers the best balance of simplicity and power."

        "@type": "Answer",
        "text": "Apache Airflow defines DAGs in Python files and requires a scheduler, workers, and metadata database. Prefect uses a cleaner Python decorator syntax with automatic retry logic and an optional hosted cloud UI. Prefect is faster to get started with; Airflow has a larger ecosystem of pre-built operators."

        "text": "Yes. Airflow with LocalExecutor runs on 2 vCPUs and 4GB RAM for light workloads. Prefect is lighter if you use Prefect Cloud for the UI. Dagster typically needs 4GB+ RAM. All three work on standard UK VPS providers like Hetzner, DigitalOcean, or OVH."
