Dandandan opened a new issue, #9587: URL: https://github.com/apache/arrow-rs/issues/9587
## Summary Pre-reserve `output.views` and `output.offsets` capacity before the dictionary decode loop to avoid per-chunk reallocation during `extend`. This is a small, independent optimization split out from the broader StringView dictionary decoding work (#9582). ## Changes - Reserve `output.views` capacity in `ByteViewArrayDecoderDictionary::read` - Reserve `output.offsets` capacity in `ByteArrayDecoderDictionary::read` ## Expected improvement ~3-25% improvement for dictionary-encoded StringView/BinaryView/String reads depending on the encoding. -- This is an automated message from the Apache Git Service.
