Common questions

Is Airflow suitable for real-time streaming?

No, Airflow is not a streaming solution. However, it is commonly used to process real-time data by pulling from streams in batches on a schedule.

What languages can I use to interact with Conductor?

Conductor provides official SDKs for Java, Python, JavaScript/TypeScript, Go, and C#.

Answer surfaced from Conductor

How does Kestra maintain workflows as code when building from the UI?

Every change made in the UI automatically updates the underlying YAML definition. You can push workflows to Git directly from Kestra, ensuring version control and CI/CD integration regardless of how workflows are created.
