描述
### Describe the usage question you have. Please include as many useful details as possible.
I am trying to use the native arrow features such as parquet read write.
currently I was trying do it with dataset JNI bridge
some missing bits:
1. how to set a filter?
I saw PR (33877) adding filter support, is that already supported or what is blocking this feature
3. how to set offset and length when reading parquet file?
any documentation regarding how this could be done ?
### Component(s)
Java
贡献指南
调研方向
从 issue 中描述的 Java dataset JNI bridge 以及原生 Arrow parquet 读写用法开始。检查 PR 33877 中的过滤器支持是否可用,以及 offset 和 length 是如何暴露的;完成的标准是 dataset 使用示例和文档能够回答这些问题。
