Module batcher 

Types for consolidating, merging, and extracting columnar update collections.

Structs

Chunker

A chunker to transform input data into sorted columns.

ColumnChunker

A chunker that consolidates Column<(D, T, R)> updates into sorted Column chunks, without round-tripping through columnation.

ColumnMerger

Counterpart to ColInternalMerger (which merges ColumnationStack chunks). Drives the merge batcher with Column-shaped chunks, no columnation detour, by way of the inherent merge_from / extract methods on Column<(D, T, R)> below.
