Module spines 

Spines specialized to contain Row types in keys and values.

Structs

RowLayout

RowRowLayout

A layout based on timely stacks

RowValLayout

ValRowLayout

Mirror of RowValLayout with the roles swapped: arbitrary Columnation keys with Row values stored as packed bytes in a DatumContainer.

Type Aliases

KeyBatcher 🔒

KeyValBatcher 🔒

Batcher matching mz_compute::typedefs::KeyValBatcher, redeclared locally so this crate does not need to depend on mz_compute.

RowBatcher

RowBuilder

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.

ValRowBuilder

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.
