Description

### 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 ?

Research direction

Start with the Java dataset JNI bridge and the native Arrow parquet read/write usage described in the issue. Check whether filter support from PR 33877 is available and how offset and length are exposed; done means a dataset usage example and documentation answer these questions.
