[R] Implements low-level bindings to Dataset classes

    XMLWordPrintableJSON

Details

    Description

      The following classes should be accessible from R:

      • class DataSource
      • class DataSourceDiscovery
      • class Dataset
      • class ScanContext, ScanOptions, ScanTask
      • class ScannerBuilder
      • class Scanner

      The end result is reading a directory of parquet files as a single stream. One should be able to re-implement https://github.com/apache/arrow/pull/5720 in R. 

      See also https://github.com/apache/arrow/pull/5675/files for another end-to-end example in C++.
