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.

affected_leaves: usize

Number of distinct leaf groups planned for this batch.

changed_leaves: usize

Number of affected leaves whose contents actually changed.

sparse_leaf_applies: usize

Number of leaf groups applied with sparse binary-search mutation.

written_nodes: usize

Unique content-addressed nodes written by the batch collector.

written_bytes: usize

Total serialized bytes for unique nodes written by the batch collector.

used_append_fast_path: bool

Whether the append-only right-edge fast path completed the batch.

used_batched_route: bool

Whether planning used the batched read routing path.

used_coalesced_rebuild: bool

Whether the multi-leaf coalesced rebuild path was used.

used_deferred_rebalancing: bool

Whether the deferred single-leaf/group rebalance path was used.

used_bottom_up_rebuild: bool

Whether the configured bottom-up rebuild path was used.

cache_written_nodes: bool

Whether newly written nodes were retained in the in-process node cache.
