描述
The Java implementation of the C Data Interface does not support non-0-offset arrays. This means that arrays like pyarrow.array([0, None, 2, 3, 4]).slice(1, 2) cannot be moved to a Java process. This is not even documented as required by the spec because it was an oversight.

貢獻指南
研究方向
從 C Data Interface 的 Java 實作開始,使用 pyarrow.array([0, None, 2, 3, 4]).slice(1, 2) 重現切片陣列範例。完成的標準是可以將非 0 偏移量的陣列傳送至 Java 程序,並涵蓋此情況以及相關的 C Data Interface 行為。
