> Allow random access to row groups in ParquetFileReader
> ------------------------------------------------------
>
> Key: PARQUET-1982
> URL: https://issues.apache.org/jira/browse/PARQUET-1982
> Project: Parquet
> Issue Type: New Feature
> Components: parquet-mr
> Reporter: Felix Schmalzel
> Priority: Minor
> Labels: parquetReader, random-access
>
> The used SeekableInputStream and all other components of the
> ParquetFileReader already support random access and row groups should be
> independent of each other.
> This would allow reusing the opened InputStream when you want to go back a
> row group. It also makes accessing specific row groups a lot easier.
> I've already developed a patch that would enable this functionality. I will
> link the merge request in the next few days.
> Is there a related ticket that i have overlooked?
