Building scalable, reliable ETL pipelines is a challenge for organizations managing large, diverse data sources. Theseus, our custom ETL framework, streamlines data ingestion and transformation by fully leveraging Databricks-native capabilities, including Lakeflow Declarative Pipelines, auto loader and event-driven orchestration. By decoupling supplier logic and implementing structured bronze, silver, and gold layers, Theseus ensures high-performance, fault-tolerant data processing with minimal operational overhead. The result? Faster time-to-value, simplified governance and improved data quality — all within a declarative framework that reduces engineering effort. In this session, we’ll explore how Theseus automates complex data workflows, optimizes cost efficiency and enhances scalability, showcasing how Databricks-native tools drive real business outcomes.
