mchades opened a new pull request, #12386: URL: https://github.com/apache/gravitino/pull/12386
### What changes were proposed in this pull request? Add the public Java API for structured Metric Views described in #12360: - Introduce `MetricRepresentation` and OSI-compatible semantic model types. - Add string-based `MetricDialects` constants and immutable builders. - Add `View#metricRepresentation()` and `ViewCatalog#createMetricView()`. - Add API unit tests for the new types and helpers. ### Why are the changes needed? Gravitino needs a typed public contract for representing Metric Views through the existing View lifecycle. This PR establishes the Java API layer; REST, persistence, clients, server-side validation, and query execution are outside its scope. Fix: #12385 ### Does this PR introduce _any_ user-facing change? Yes. It adds new `@Unstable` public Java APIs for creating and reading structured Metric Views. ### How was this patch tested? - `./gradlew :api:test :api:javadoc :api:spotlessCheck` -- This is an automated message from the Apache Git Service.
