Unlocking Data Portability: Preventing Catalog Lock-in with REGISTER and UNREGISTER APIs

This post introduces the REGISTER and UNREGISTER APIs as a new open standard for data catalog management. It details how these APIs allow for the safe transfer of a table's catalog management without copying the underlying data, thereby preventing catalog lock-in and enabling data portability. The technical contribution lies in defining these new API endpoints and their behavior to facilitate seamless migration of cataloged tables between different catalog systems.
