----------------------------------------
thanks for the heads up [~emkornfield], i'll keep an eye on this so that I can
update the Go implementation once a decision is reached.
> [C++] Statistics::num_values() is misleading
> ---------------------------------------------
>
> Key: PARQUET-2099
> URL: https://issues.apache.org/jira/browse/PARQUET-2099
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-cpp
> Reporter: Micah Kornfield
> Priority: Major
> Fix For: cpp-6.0.0
>
>
> num_values() in statistics seems to capture the number of encoded values.
> This is misleading as everyplace else in parquet num_values() really
> indicates all values (null and not-null, i.e. the number of levels).
> We should likely remove this field, rename it or at the very least update the
> documentation.
