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.

Modules

bytes_container 🔒

A [u8]-specialized container.

dictionary 🔒

A Row-specialized container using dictionary compression.

offset_opt 🔒

row_codec 🔒

Traits abstracting the processes of encoding and decoding row-encoded byte sequences.

spines 🔒

Spines specialized to contain Row types in keys and values.

Structs

DatumContainer

DatumSeq

A reference that can be resolved to a sequence of Datums.

OffsetOptimized

Statics

DICTIONARY_COMPRESSION

Enable per-column dictionary compression in row containers.

Functions

offset_list_size 🔒

Helper to compute the size of an OffsetList in memory.

RowRowBatcher

RowRowBuilder

RowRowColPagedBuilder

RowRowBuilder variant that consumes Column chunks. Pairs with Col2ValPagedBatcher for the spillable arrange path. This is the stock (non-dictionary) builder; dictionary-compressing the paged path is a follow-up.

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.
