[jira] [Resolved] (PARQUET-1982) Allow random access to row groups
in ParquetFileReader
[ https://issues.apache.org/jira/browse/PARQUET-1982?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gabor Szadovszky resolved PARQUET-1982.
---------------------------------------
Resolution: Fixed
> 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
> Assignee: 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?
