Overview

It’s magic.

Go from zero to Mage hero in under a minute. We'll walk you through installing Mage and running your first pipeline. 🦸‍♀️

Quickstart

Every user experience and technical design decision adheres to these principles.

Details about how the Mage file directory works and how typical projects are structured.

Project Structure

Pipelines

Pipeline Management

Each block in a pipeline maps to an individual file within a project. Blocks can be reused and shared across multiple pipelines within the same project.

Use the output of a block to dynamically create more blocks.

Dynamic blocks

Data integration is the process of synchronizing data between two systems.

There are many ways to configure your data integration pipeline.

Configure data integration pipelines

Load data from data integration sources and export to data integration destinations as blocks inside batch pipelines.

Batch pipelines

Configure triggers in triggers.yaml under pipeline folder.

Configure triggers in code

You can trigger another pipeline from a block within a different pipeline.
