[Python] pa.union() mode argument unintuitive

    XMLWordPrintableJSON

    Details

      Description

      >>> pa.union([pa.field('x', pa.int16())], 'sparse')
      UnionType(union[dense]<x: int16=0>)
      >>> pa.union([pa.field('x', pa.int16())], 'dense')
      UnionType(union[dense]<x: int16=0>)
      >>> pa.union([pa.field('x', pa.int16())], 42)
      UnionType(union[dense]<x: int16=0>)
      

      I would suggest allowing "sparse" and "dense" strings as aliases to the internal enum values, and disallowing everything else.
