Uwe L. Korn commented on PARQUET-579:
-------------------------------------
That's already resolved with the above issue. I thought this would also include
file-level statistics but it seems that the most upper level on which we have
statistics in Parquet is the RowGroup.
> Add API for writing Column statistics

> Issue Type: New Feature

> Reporter: Uwe L. Korn
> Assignee: Artem Tarasov

> In the initial implementation of ParquetFileWriter, there is no support for
> writing/computing statistics.
> * Write an API so that the user can specify statistics on their own.
> * Add a convenience class that calculates the statistics during write.
