Dimitrij Denissenko commented on ARROW-9137: -------------------------------------------- This applies not just to Ruby but also to Python. > [GLib][Ruby] Allow to read Parquet files in chunks (by RowGroup) > ---------------------------------------------------------------- > > Key: ARROW-9137 > URL: https://issues.apache.org/jira/browse/ARROW-9137 > Project: Apache Arrow > Issue Type: Improvement > Components: GLib, Python, Ruby > Affects Versions: 0.17.1 > Reporter: Dimitrij Denissenko > Priority: Major > > At the moment only `gparquet_arrow_file_reader_read_table` is exported which > requires the reader to load all row-groups. Additionally, it would be > extremely helpful to have access to the `ReadRowGroup` method which would > allow reading parts of the file without having to load everything into memory. -- This message was sent by Atlassian Jira (v8.3.4#803005)
