Parquet cpp status

[Chang Chen <ba...@gmail.com>]

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
Chang

Yes,  JIRA is good source for tracking progress, obviously it is not good
for understanding the overview or summary, such as the current supported
features.

Thanks for your reply

Cheers
Chang

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.
