Structs

BatcherHooks

Callbacks you can install on the ChunkBatcher.

BoolOptSliceIter

Lazily yields Option<bool> for one component batch (span) of a boolean column: None for null slots, Some(value) otherwise.

Chunk

Dense arrow-based storage of N rows of multi-component multi-temporal data for a specific entity.

ChunkBatcher

Implements an asynchronous batcher that coalesces PendingRows into Chunks based upon the thresholds defined in the associated ChunkBatcherConfig.

ChunkBatcherConfig

Defines the different thresholds of the associated ChunkBatcher.

ChunkBuilder

Helper to incrementally build a Chunk.

ChunkComponentIter

The actual iterator implementation for Chunk::iter_component.

ChunkComponentIterItem

The underlying item type for ChunkComponentIter.

ChunkComponents

ChunkIndicesIter

ChunkSplitConfig

See Chunk::split_chunk_if_needed.

LatestAtQuery

A query at a given time, for a given timeline.

NativeOptSliceIter

Lazily yields Option<T> for one component batch (span) of a primitive column: None for null slots, Some(value) otherwise.

PendingRow

A single row’s worth of data (i.e. a single log call).

RangeQuery

A query over a time range, for a given timeline.

RangeQueryOptions

StringOptSliceIter

Lazily yields Option<ArrowString> for one component batch (span) of a string column: None for null slots, Some(string) otherwise (including Some("") for explicitly-empty strings).

TimeColumn

TimeColumnBuilder

Helper to incrementally build a TimeColumn.

UnitChunkShared

A ChunkShared that is guaranteed to always contain a single row’s worth of data.

Enums

BatcherFlushError

An error that can occur when flushing.

ChunkBatcherError

Errors that can occur when creating/manipulating a ChunkBatcher.

ChunkError

Errors that can occur when creating/manipulating a Chunks, directly or indirectly through the use of a crate::ChunkBatcher.

TimeColumnError

Errors when deserializing/parsing/reading a column of time data.

Traits

ChunkComponentSlicer

A ChunkComponentSlicer knows how to efficiently slice component batches out of a Chunk column.

Type Aliases

ChunkBatcherResult

ChunkResult

ChunkShared

A simple type alias for an Arc<Chunk>.
