EXPLAIN and PROFILE

Wiki / Cypher query language

EXPLAIN / PROFILE

Create the relevant index first. A parameter used by the query still needs a value from your driver or embedding API.

Prefix any query with EXPLAIN to see the chosen plan without executing it. The plan lists operators and, for each MATCH anchor, the scan strategy the planner picked (index seek / label scan / all-nodes scan). The anchor may be either end of the pattern — the operator line shows the scan of the end the planner chose.

EXPLAIN MATCH (p:Person {email: $e}) RETURN p;
// Match: NodeIndexSeek(:Person .email)
// ProduceResults

PROFILE <query> currently runs the query normally (detailed per-operator profiling metadata is future work — see Compatibility and limitations).
