Module persistent_graph 

LanceDB-backed persistent graph engine.

Replaces the in-memory PropertyGraph (petgraph) with a persistent graph stored in LanceDB datasets. The graph survives process restarts, scales beyond RAM, and supports indexed adjacency queries.

Datasets

• graph_nodes — one row per graph node (memory)
• graph_edges — one row per directed edge

Structs

BfsResult

Result of a batch BFS traversal.

CausalBfsRow

A single row from PersistentGraph::deep_causal_bfs.

PersistentGraph

Persistent graph backed by LanceDB datasets.
