URL: https://github.com/apache/arrow-rs/issues/7363

   **Is your feature request related to a problem or challenge? Please describe 
what you are trying to do.**
   
   - As described on https://github.com/apache/arrow-rs/pull/6921 
   
   There are some times where enabling row filter actually slows down the 
parquet decoding and one reason for this is having to decompress (e.g. ZSTD) 
the pages twice
   
   
   **Describe the solution you'd like**
   https://github.com/apache/arrow-rs/pull/6921 has a cache to avoid this 
second decode
   
   I would like to get that PR merged
   
   Steps:
   - [ ] Test performance
   - [ ] Polish + merge
   
   
   **Describe alternatives you've considered**
   <!--
   A clear and concise description of any alternative solutions or features 
you've considered.
   -->
   
   **Additional context**
   
   I am filing this as a separate ticket as there are a lot of other ideas on 
https://github.com/apache/arrow-rs/pull/6921 that make it kind of hard to follow
