mchades opened a new pull request, #14038: URL: https://github.com/apache/gravitino/pull/14038
### What changes were proposed in this pull request? Add a design document for schema-level Semantic Model metric discovery, covering API contracts, authorization, storage alternatives, stable metric identities, and transactional read/write paths. The selected design stores definition fields separately in model snapshots and maintains a metric identity table. ### Why are the changes needed? Clients currently load each Semantic Model to collect its metrics. The proposal provides schema-level discovery without transferring unrelated model content and defines stable internal metric identity across model updates. Fixes #14037. Part of #14036 under #12209. ### Does this PR introduce _any_ user-facing change? No. This PR adds a design document only. ### How was this patch tested? Reviewed against the existing API, DTO, authorization, and storage code. Checked Markdown structure, reference links, JSON examples, table alignment, and whitespace. No runtime tests were run for this documentation-only change. -- This is an automated message from the Apache Git Service.
