Struct GraphTuning 

pub struct GraphTuning {
    pub max_visited: usize,
    pub max_depth: usize,
    pub lcc_high_degree_threshold: usize,

}

Graph engine tuning (traversal limits, LCC algorithm).

Fields

max_visited: usize

max_depth: usize

lcc_high_degree_threshold: usize

lcc_sample_pairs: usize

varlen_max_results: usize

Hard cap on results emitted from a single variable-length MATCH ([*min..max]) expansion. When an expansion would exceed this it truncates at the current hop boundary and surfaces a resume cursor so the remainder is paged across follow-up rounds (cross-shard or local) — no row is silently dropped. Bounds peak per-expansion result allocation.

varlen_max_frontier: usize

Hard cap on the live (per-hop) frontier of a single variable-length MATCH expansion. When a single hop would grow the frontier past this it truncates and pages via resume, bounding peak intermediate allocation on dense / bidirectional traversals.

max_gathered_algo_edges: usize

Hard cap on the distinct edges a gathered graph algorithm collects from every owner before it runs on one core. The algorithm needs every edge in one CSR, so a run over more edges is refused with the edge count rather than answered from part of the graph.
