🎓 A practical guide to building production-ready data platforms using pure Python tools, demonstrated through Star Wars franchise analytics.

Speakers:
Eric Thanenthiran

Description:
This presentation examines the implementation of pure Python open source data platforms, focusing on practical architecture and tooling choices for small to medium-scale data operations. Thanenthiran demonstrates the construction of a complete data stack using Star Wars datasets as an example, incorporating five key components: data sources, pipelines, data storage, transformation, and orchestration. The stack utilizes DLT for data pipelines, DuckDB for storage, DBT for transformations, Dagster for orchestration, and Streamlit for visualization. The presentation addresses critical considerations in data platform development, including schema evolution, data quality testing, and lineage tracking. Particular attention is given to the medallion architecture approach, progressing data through raw, staging, domain, and curated layers. The implementation demonstrates handling both API and file-based data sources, transformation logic management, and effective data visualization for non-technical stakeholders. While the demonstrated stack is optimized for batch processing of datasets up to tens of gigabytes, Thanenthiran discusses considerations for scaling and alternatives for larger implementations. The presentation emphasizes practical implementation patterns and real-world considerations in data platform development, providing insights for engineers building initial data infrastructure.
