public class BuildVectorsFromMetadata extends Object
VectorContainerwhich is the end product of this builder.
Vectors are built recursively by walking the tree that defines a row's structure. For a classic relational tuple, the tree has just a root and a set of primitives. But, once we add array (repeated), variant (LIST, UNION) and tuple (MAP) columns, the tree grows quite complex.
