### Discussed in https://github.com/apache/arrow-rs/discussions/8300 <div type='discussions-op-text'> <sup>Originally posted by **duarten** September 9, 2025</sup> It seems we always [re-encode dictionaries](https://github.com/apache/arrow-rs/blob/main/parquet/src/arrow/arrow_writer/byte_array.rs#L342) when writing row groups to Parquet. Would it make sense to avoid this for cases where all/most dictionary values appear in all row groups?</div> Potentially related: - https://github.com/apache/arrow-rs/pull/9520 - https://github.com/apache/arrow-rs/pull/2322 -- This is an automated message from the Apache Git Service.
