Mage

You can install Mage using Docker, pip, or conda.

Setup

Setup and install

We welcome all contributions to Mage; from small UI enhancements to brand new cleaning actions. We love seeing community members level up and give people power-ups!

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

Core design principles

These are the fundamental concepts that Mage uses to operate.

Core abstractions

Orchestration

Data 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.

Overview

Write your code for fetching data from a remote source or loading it from disk.

Data loader

Use these blocks to clean, transform, and enhance data from other blocks.

Transformer

Once you’re done transforming your data, write code in these types of blocks to store that data or to train models and store those models elsewhere.

Data exporter

Use these blocks to experiment and write throw away code.

Scratchpad

A sensor is a block that continuously evaluates a condition until it’s met or until a period of time has elapsed.

Sensor

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

Dynamic blocks

An extension block adds extra functionality to blocks in your pipeline.

Extension

Extension block

Data integration is synchronizing data from an external system to an internal system or vice versa.

A source is a system that you want to load data from and synchronize it into another system. A source can be a 3rd party API, SaaS, database, data warehouse, or a data lake.

How to build a data integration pipeline

Build pipelines that ingest data from event streaming sources like Kafka.

Callbacks

SQL blocks

R blocks

Custom blocks are generic blocks for organizing your pipeline that may not fit into any of the other category of blocks. Unlike Scratchpad blocks, Custom blocks are executed as part of the pipeline.

Custom

Use 3rd party Python packages in your project and pipelines.

Install Python packages

You can import any Python code from any file that is in your Mage project directory.

Custom files

Import your own Python code

Build pipelines that ingest data from event streaming sources like RabbitMQ.

Every data loader and transformer block has data validation capabilities built-in.

Data validation

Test the data produced by pipeline blocks using Great Expectations.

Secrets

Use GCP credentials locally when developing.

Setting up Git on Cloud

Mage can automatically keep track of previous versions of a file. Any update to the contents of a file will create a new version that can be used to restore a file to a previous state. This also includes changes to a pipeline.

File versions

File versioning in Mage

Mage is designed and built to be cloud native.

Multi-development environment in the cloud
