/**
* Nested data column with optimized support for simple arrays. Not actually v5 in the segment since columns are now
* serialized using {@link org.apache.druid.segment.serde.NestedCommonFormatColumnPartSerde} instead of the generic
* complex type system.
*
* Not really stored in a segment as V5 since instead of V5 we migrated to {@link NestedCommonFormatColumn} which
* specializes physical format based on the types of data encountered during processing, and so versions are now
* {@link NestedCommonFormatColumnSerializer#V0} for all associated specializations.
