Crate mz_row_spine 

Types and traits in support of containers for row-encoded byte slices.

This includes the vanilla bytes_container that holds byte slices in contiguous allocations, as well as a dictionary encoding wrapper that is able to rewrite the byte slices to use spare tags in each column to reference common values.

RowRowBatcher

RowRowBuilder

RowRowColPagedBuilder

RowRowBuilder variant that consumes Column chunks. Pairs with Col2ValPagedBatcher for the spillable arrange path. Installs a dictionary codec at seal time, gathering statistics from the sealed Column chain, so paged arrangements compress on the same footing as the columnation-fed RowRowBuilder.

ValRowColPagedBuilder

ValRowBuilder variant that consumes Column chunks. Pairs with Col2ValPagedBatcher<K, Row, T, R> for the spillable arrange path where keys are arbitrary Columnar values (e.g. UpsertKey) and values are packed Row bytes. Installs a dictionary codec on the value container at seal time, gathering statistics from the sealed Column chain; keys are not Row-shaped and so are left uncompressed.
