kou opened a new pull request, #49209: URL: https://github.com/apache/arrow/pull/49209
### Rationale for this change This focuses on implementing base dictionary delta message support mechanism. So this adds support for only UTF-8 array as dictionary. Other arrays will be supported in follow-up tasks. ### What changes are included in this PR? * Add support for `ArrowFromat#slice` (But it's not completed. It just works partially.) * If the second record batch includes an updated dictionary (new entries are appended), these appended entries are sliced and they are only written as delta. ### Are these changes tested? Yes. ### Are there any user-facing changes? Yes. -- This is an automated message from the Apache Git Service.
