[C++] Review logic around automatic assignment of field_id's

    XMLWordPrintableJSON

    Details

      Description

      At schema deserialization (from Thrift) time, we are assigning a default field_id to the Schema node based on a depth-first ordering of notes. This means that a round trip (load, then write) will cause field_id's to be written that weren't there before. I'm not sure this is the desired behavior.

      We should examine this in more detail and possible change it. See also discussion in ARROW-7080 https://github.com/apache/arrow/pull/6408
