There are no such documents -- all of the work / TODOs are tracked in JIRA. If you find something you need that does not have a corresponding JIRA issue feel free to open one.

Hi 

I am trying to find doc about current parquet-cpp current status.  i googled it, but i didn't find any useful information.

here are what i concerned about:

#1  column indexes (https://issues.apache.org/jira/browse/PARQUET-1201), the corresponding java implementation already supported it last year, though it wasn't pushed to repo.

#2  A vectorized column reader interface which can be integrated in JAVA.

#3 the feature was illustrated here(https://www.dremio.com/webinars/columnar-roadmap-apache-parquet-and-arrow/),  a better predict push down algorithm.

Thanks
