REGISTER API
A data catalog API that allows tables already residing in object storage to be registered in a catalog by pointing to their metadata files, without copying the underlying data. It is a core mechanism for achieving catalog portability and enabling tables to be shared across multiple catalogs.
Timeline (last 90 days)
The REGISTER API allows users to register a table that already exists in object storage into a target catalog by pointing to its metadata file, without needing to rewrite or copy data.
The combination of the REGISTER and UNREGISTER APIs implements the design philosophy of the catalog as a pluggable component, making the catalog a management layer that can be switched at any time.
When multiple catalogs register the same table simultaneously, concurrent writes may cause metadata conflicts.
