thswlsqls opened a new pull request, #17069:
URL: https://github.com/apache/iceberg/pull/17069

   
   Closes #17068
   
   ## Summary
   
   - `loadView()` built a `ViewOperations` to check existence via 
`ops.current()`, then discarded it and called `newViewOps(identifier)` again to 
construct the returned `BaseView`, reloading view metadata from the metastore 
twice per call.
   - Reuse the `ops` from the existence check instead of creating a second 
instance.
   - Matches `BaseViewBuilder.create`/`replace` in the same file and the parent 
`BaseMetastoreCatalog.loadTable()`, which already reuse `ops` this way.
   
   ## Testing done
   
   - Added 
`TestBaseMetastoreViewCatalogLoadView#loadViewReusesOpsFromExistenceCheck`, 
asserting `newViewOps` is called once (was twice) per `loadView()`.
   - `./gradlew :iceberg-core:check` — passed (test + spotlessCheck + 
checkstyle + errorProne).
   - `./gradlew :iceberg-core:revapi` — passed (backward compatible, no 
signature change).
