TreeCat introduces a purpose-built database engine specifically designed to serve as a catalog system for large-scale, heterogeneous data environments.

• Addresses limitations in existing solutions and lakehouse storage formats
• Features optimized data models and storage formats for catalog metadata
• Implements specialized query execution and concurrency control protocols
• Provides a dedicated solution for managing complex metadata at scale

This research matters because effective catalog systems are increasingly critical for organizations managing massive volumes of diverse data across multiple specialized compute engines. TreeCat's approach enables more efficient data discovery, governance, and utilization in modern data architectures.
