Module columnar 

Container for columnar data.

Modules

batcher

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

builder

A container builder for columns.

consolidate

A ContainerBuilder that consolidates (D, T, R) updates and emits columnar containers.

Enums

Column

A container based on a columnar store, encoded in aligned bytes.

Constants

SHIP_WORDS 🔒

Words per 2 MiB. length_in_words returns serialized size in u64 units, so this is the page count we round up to. Picked to match builder::ColumnBuilder’s output granularity so chunks shipped from the merger and chunks shipped from the builder are sized comparably.

Functions

at_serialized_capacity 🔒

Returns true once the serialized size of borrow is within 10% of the next SHIP_WORDS boundary.

columnar_exchange

An exchange function for columnar tuples of the form ((K, V), T, D). Rust has a hard time to figure out the lifetimes of the elements when specified as a closure, so we rather specify it as a function.

Type Aliases

Col2KeyBatcher

A batcher for columnar storage with unit values.

Col2ValBatcher

A batcher for columnar storage.
