Situation

Parquet files are organized into row groups. These chunks of a single parquet file then can be read instead of reading the whole file. The PIOJ should support reading specified row groups.

Acceptance Criteria

  • Chunked Parquet reader is implemented
  • In addition, Parquet file virtual splitter is provided
  • Tests are added
