             Summary: [Format] In C interface, clarify resource management for consumers needing only a subset of child fields in ArrowArray
                 Key: ARROW-8368
                 URL: https://issues.apache.org/jira/browse/ARROW-8368
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Format
            Reporter: Wes McKinney


The current implication of the C Interface is that only moving a single child out of an ArrowArray is allowed. 

Questions:

* Should it be allowed to move multiple children, as long as they are moved at the same time, and the parent is released after?
* In the event that children have disjoint internal resources, should there be a clarification around moved children having their resources released independently?
