[jira] [Created] (ARROW-11601) [C++][Dataset] Expose pre-buffering in ParquetFileFormatReaderOptions

David Li created ARROW-11601:
--------------------------------

             Summary: [C++][Dataset] Expose pre-buffering in ParquetFileFormatReaderOptions
                 Key: ARROW-11601
                 URL: https://issues.apache.org/jira/browse/ARROW-11601
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
    Affects Versions: 3.0.0
            Reporter: David Li
            Assignee: David Li


This can help performance on high-latency filesystems. However, some care will be needed as then we won't be able to create one Arrow reader per Parquet row group anymore.
