Profiling Queries with EXPLAIN and PROFILE

Learn to read Cypher execution plans using EXPLAIN and PROFILE to diagnose and fix slow queries in Neo4j.

You Cannot Tune What You Cannot See

Before optimizing a query, you must understand how Neo4j executes it. The EXPLAIN and PROFILE keywords reveal the execution plan.

EXPLAIN shows the planned operators without actually executing the query. Use it to inspect plans safely, even for writes.

EXPLAIN
MATCH (p:Person {name: 'Alice'})-[:FRIEND]->(f)
RETURN f.name;
