- Block-based pipeline design (Data Loader, Transformer, Data Exporter)
- Real-time kernel execution with instant block output preview
- Backfill, trigger, and schedule pipelines from the UI
- Streaming pipeline support for Kafka, Kinesis, and websockets
- Mage Pro cloud platform for team collaboration and managed infra
Real-World Workflows
Interactive data pipeline development
- 1Launch Mage locally with Docker and open the browser IDE
- 2Create a new pipeline and add a Data Loader block for Postgres
- 3Add a Transformer block to clean and reshape the data
- 4Add a Data Exporter block to write to Snowflake or S3
- 5Run and validate the pipeline end-to-end in the IDE
ML feature engineering pipeline
- 1Load raw feature data from S3 with a Data Loader block
- 2Write feature transformations in Python Transformer blocks
- 3Save outputs as Parquet features to a feature store
- 4Schedule daily runs and monitor in Mage's pipeline view
