adamreeve opened a new issue, #41225: URL: https://github.com/apache/arrow/issues/41225
### Describe the enhancement requested This is a follow up to #40517, which made round-tripping of sliced arrays via the IPC format work. When writing list arrays and binary/string arrays the full values buffer is written and the value offsets and validity buffer are sliced, but to reduce file sizes the value buffer should be sliced and the value offsets adjusted. Eg. see the [C++ implementation](https://github.com/apache/arrow/blob/18c74b0733c9ff473a211259cf10705b2c9be891/cpp/src/arrow/ipc/writer.cc#L316). ### Component(s) C# -- This is an automated message from the Apache Git Service.
