"""
The node performs a vertical, rowwise, split of :ref:`ADAF`. The vertical
split, or VSplit, is the inverse operation compared to the vertical join,
see :ref:`VJoin ADAF`.
The vertical split operation is only applied on the content of the metadata
and result containers. The timeseries container is not included, since the
inverse operation, VJoin, is not defined for this container. The content of
the metadata and the result containers are tables and the vertical split of
these containers follows the procedure described in :ref:`VSplit Table`.
For the split to be well defined, the Input Index column is required in
metadata and result containers.
