[jira] [Created] (ARROW-14025) [R][C++] PreBuffer is not enabled when scanning parquet via exec nodes

Weston Pace created ARROW-14025:
-----------------------------------

             Summary: [R][C++] PreBuffer is not enabled when scanning parquet via exec nodes
                 Key: ARROW-14025
                 URL: https://issues.apache.org/jira/browse/ARROW-14025
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++, R
            Reporter: Weston Pace


In ExecNode_Scan a ScanOptions object is built up.  If we are reading parquet we should enable pre-buffering.  This is done by creating a ParquetFragmentScanOptions object and enabling pre-buffering.

Alternatively, we could just default pre-buffering to true for asynchronous scans of parquet data.
