>                 Key: PARQUET-1022
>                 URL: https://issues.apache.org/jira/browse/PARQUET-1022
>             Project: Parquet
>          Issue Type: New Feature
>          Components: parquet-cpp
>    Affects Versions: cpp-1.1.0
>            Reporter: yugu
>            Priority: Major
>
> As said, currently trying to work out a append feature for parquet files in c++.
> (been searching through repo etc, can't find example tho..)
> Current solution is to (assume no schema changes that is):
> Read in metadata
> Change metadata based on appended rows+ original rows
> Append a new row group (or multiple row group writer)
> Write the new rows.
> ---
> The problem is that, is approached this way, the original last row group may not be complete filled. Was wondering if there is a fix or I'm using the api wrong...
> Thanks ! : D
