itsmehotpants opened a new pull request, #22697: URL: https://github.com/apache/kafka/pull/22697
### Motivation The `Cast` SMT only supports top-level fields. Nested field casting via dotted notation (e.g. `outer.inner:int32`) is not supported. This was noted in an internal TODO comment but never surfaced to users. ### Changes `connect/transforms/src/main/java/org/apache/kafka/connect/transforms/Cast.java` - **`OVERVIEW_DOC`**: note that only top-level fields are supported - **`spec` ConfigDef description**: same clarification Documentation strings only. No logic, behaviour, or API change. ### Committer checklist - [x] No new public API or behaviour change - [x] No new tests required (doc-only change) - [x] Internal TODO comment preserved for future nested-field support -- This is an automated message from the Apache Git Service.
