mapleFU opened a new issue, #45594: URL: https://github.com/apache/arrow/issues/45594
### Describe the enhancement requested memcpy a short string multiple times is slow. `DeltaLengthByteArray` stores all payload together, so the payload can be copied once. Previous: https://github.com/apache/arrow/blob/main/cpp/src/parquet/decoder.cc#L1678-L1713 New: 1. Add a builder method for "Build with offsets" or "Build with length", and put whole buffer 2. Copying the data once I've verified that this can bring Decoder 4x faster ### Component(s) C++, Parquet -- This is an automated message from the Apache Git Service.
