Store-neutral execution stats for a batch mutation.

These counters describe tree work and write amplification before any storage-engine-specific buffering, compaction, or object layout effects.

Fields

input_mutations: usize

Number of mutations supplied by the caller before preprocessing.

effective_mutations: usize

Number of mutations left after sort/deduplication preprocessing.

preprocess_input_sorted: bool

Whether the input mutation keys were already sorted before preprocessing.

entries_streamed: usize

Logical entries streamed through canonical emitters.

nodes_read: usize

Content-addressed nodes loaded by the write.

written_nodes: usize

Unique content-addressed nodes written by the write.

nodes_reused: usize

Existing content-addressed nodes reused without rewriting.

bytes_read: usize

Serialized node bytes loaded by the write.

written_bytes: usize

Total serialized bytes for unique nodes written by the write.

resync_distance_entries: usize

Entries replayed before canonical CID resynchronization.

resync_distance_nodes: usize

Nodes traversed before canonical CID resynchronization.

used_key_stable_fast_path: bool

Whether a key-stability proof enabled direct value replacement.

used_batched_value_update_path: bool

Whether value updates used batched canonical route hydration.

parallel_width: usize

Maximum CPU partition width actually used by an admitted leaf/island executor. Ordered store-read fan-out is reported by store metrics.

parallel_tasks: usize

Number of logical independent CPU partitions scheduled by this write.

structural_islands: usize

Number of structural mutation islands planned by this write.

coalesced_islands: usize

Number of structural mutation islands coalesced before replay.
