## When it is useful

Create MotherDuck data shares: zero-copy, read-only metadata clones of a database. Not S3 sharing and not DuckDB ATTACH of a file (duckdb-attach-db). Recipients ATTACH the share read-only.

## The Catch

Zero-copy metadata clones, not S3 sharing, not DuckDB ATTACH of a file. Distinct from duckdb-attach-db and from motherduck-load-data. Lite still 3 users / 2 service accounts.
