             Summary: [C++] Configure a custom handler for rows with incorrect column counts
                 Key: ARROW-12673
                 URL: https://issues.apache.org/jira/browse/ARROW-12673
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Nate Clark


Currently when a row does not have the correct number of columns an error is generated and parsing stops. It would be better if this behavior was customizable depending on the caller so that rows could either be ignored or altered to have the correct column count.

Ideally there would be some builtin handlers for this but it would be good for the caller to be able to implement their own handler if they wanted to collect the malformed rows and report them to a different component or maybe add fields based on the existing fields in the row.
