ROOT::Experimental::RColumnGroupDescriptor Class Reference

Meta-data for a sets of columns; non-trivial column groups are used for sharded clusters.

Clusters can span a subset of columns. Such subsets are described as a column group. An empty column group is used to denote the column group of all the columns. Every ntuple has at least one column group.
