Zouxxyy opened a new pull request, #7843: URL: https://github.com/apache/paimon/pull/7843
### Purpose Follow-up of #7789. Extend `SchemaMergingUtils.diffSchemaChanges` to emit precise `AddColumn` for new struct fields nested inside `ARRAY` element / `MAP` value, instead of a coarse `UpdateColumnType` rewriting the whole nested type. Falls back to `UpdateColumnType` when a nested field is removed or a map key type changes. ### Tests - `SchemaMergingUtilsTest` - `MergeIntoTableTestBase` -- This is an automated message from the Apache Git Service.
