Frequently Asked Questions

General Questions

What is Kestra?

Kestra is an open-source orchestrator designed to bring Infrastructure as Code (IaC) best practices to all workflows — from those orchestrating mission-critical operations, business processes, and data pipelines to simple Zapier-style automation. Built with an API-first philosophy, Kestra enables users to define and manage data pipelines through a simple YAML configuration file. This approach frees you from being tied to a specific client implementation, allowing for greater flexibility and easier integration with various tools and services.

What is a declarative orchestrator?

A declarative orchestrator is a system that allows you to define and manage complex workflows using a high-level, descriptive language. Instead of specifying the exact steps and sequences to achieve a specific outcome, a declarative orchestrator lets you define the desired end state and the system figures out how to reach it.

Kestra is a declarative orchestrator designed for managing all kinds of workflows. It uses YAML (Yet Another Markup Language) to define workflows in a human-readable and structured format. Kestra workflows consist of tasks and triggers that represent various data processing operations, connected by data dependencies and flow control structures.

What are the advantages of a declarative orchestrator?

By using a declarative approach, Kestra simplifies the development, maintenance, and scalability of workflows. It allows you to focus on the high-level goals and objectives of your data workflows, while Kestra takes care of executing the tasks and handling errors, retries, and parallelism.

Some key benefits of using Kestra as a declarative orchestrator include:

  1. Improved readability and maintainability: Declarative workflows are easier to understand and modify, making it simpler for teams to collaborate and maintain their data pipelines over time.
  2. Enhanced flexibility: Declarative orchestration enables easy modification and extension of workflows as requirements change, without the need for extensive refactoring.

Who can benefit from using Kestra?

Kestra is perfect for data engineers, developers, data scientists, and anyone who needs to process, manage, and orchestrate workflows across multiple systems.
