public class NestedDataColumnV5<TKeyDictionary extends Indexed<ByteBuffer>,TStringDictionary extends Indexed<ByteBuffer>>
extends CompressedNestedDataComplexColumn<TKeyDictionary,TStringDictionary>

Nested data column with optimized support for simple arrays. Not actually v5 in the segment since columns are now serialized using NestedCommonFormatColumnPartSerde instead of the generic complex type system.

Not really stored in a segment as V5 since instead of V5 we migrated to NestedCommonFormatColumn which specializes physical format based on the types of data encountered during processing, and so versions are now NestedCommonFormatColumnSerializer.V0 for all associated specializations.
