SnapshotUtils

public static record SnapshotUtils.DataColumnCopy(ChunkSource.WithPrev<? extends Values>[] sources, WritableColumnSource<?>[] destinations)
extends Record

The parallel sources and destinations of a copy of data columns into result columns. Copying every column together lets sources that share state, such as a row redirection, share its lookups.
