Materializing Multi-Asset REST API Sources with dlt, Dagster, and DuckDB

The text discusses the integration of two open-source projects, Dagster and dlt, for building multi-asset REST API sources. The authors explore three integration patterns for using dlt within the Dagster orchestration framework to materialize multiple source API endpoints as multi-assets. They provide examples in Python, showcasing how to use dlt with Dagster to extract data from a PokeAPI, load it into a DuckDB database, and utilize the DuckDB UI for querying and exploring the data. The authors highlight the benefits of using this integration, including faster experimentation and prototyping, more robust testing, easier collaboration, and greater focus on business value. They also discuss the tradeoffs between different approaches and emphasize the importance of choosing an approach that balances control, maintainability, and framework coupling according to specific needs.
