Module trace 

The TRACE face of the columnar subsystem: the columnar data arranged as a differential-dataflow trace.

Under the hood this is a Chunk implementation (ColChunk, an UpdatesTyped trie, resident or paged), plugged into the generic chunk harness. The exported names are the BATCH/TRACE vocabulary DD arranges with — Spine, Batcher, Builder, Chunker — so callers work in trace terms, not chunk-implementation terms.

• chunk — ColChunk: the Chunk impl (cursor + merge/extract/advance/settle).
• chunker — melds RecordedUpdates streams into ColChunk batches.
• spill — per-worker page-out control (Chunk::settle’s spill hook).

Re-exports

pub use chunk::ColChunk;

Modules

chunk

chunker

The container→batch chunker for the columnar trace.

spill

Per-worker spill control for the columnar Chunk trace.

Type Aliases

Batcher

The columnar merge batcher (the chunk harness’s MergeBatcher over ColChunk).

Builder

Chunker

The input chunker: melds RecordedUpdates<U> streams into ColChunk<U> batches.

Spine

The columnar trace: a spine of Rc-shared ColChunk batches.
