It's possible and sometimes useful to use reuse a nested vector that was populated in a previous ComplexWriter. The new ComplexWriter should be aware of the fields that are present in the vector. As it is right now, if a particular column were determined to be a specific type (or a union type), but the new writer finds a new type, the original type may be thrown out. What should happen is that the type should be promoted to union (or have a new subtype added to the union field). **Reporter**: [Steven Phillips](https://issues.apache.org/jira/browse/ARROW-326) / @StevenMPhillips <sub>**Note**: *This issue was originally created as [ARROW-326](https://issues.apache.org/jira/browse/ARROW-326).
