Module spines 

Spines specialized to contain Row types in keys and values.

Structs

RowLayout

Layout for key-only Row updates. DC is the diff BatchContainer, a columnation stack by default.

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

ArcOrdKeyBuilder

Builder pairing with ArcOrdKeySpine.

ArcOrdKeySpine

Generic Arc-backed key-only spine. See ArcOrdValSpine.

ArcOrdValBuilder

Builder pairing with ArcOrdValSpine.

ArcOrdValSpine

A generic Arc-backed key/value spine, for callers outside mz_compute that need an arrangement over non-Row-specialized types. The Arc handle rides on the local ArcBatch newtype, so no differential-side Arc batch impls are required.

FundedValRowSpine

A ValRowSpine whose optional exertion is funded by its input.

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 ColumnBody chunks. Pairs with any batcher whose chains are bodies, spillable (AccountedChunkBatcher behind an UnchunkBuilder) or resident (Col2ValColBatcher) alike, so the Paged in the name records where it started rather than a restriction. Installs a dictionary codec at seal time, gathering statistics from the sealed chain, so columnar arrangements compress on the same footing as the columnation-fed RowRowBuilder.

RowRowSpine

RowSpine

Key-only Row spine. DC is the diff container, see RowLayout.

ValRowBatcher

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.
