A decision guide for choosing between Neo4j GDS Louvain and custom Cypher for community detection, covering performance trade-offs, memory constraints, and implementation.
Learn how to match Neo4j index types to query patterns and integrity needs, avoid unnecessary scans, and validate choices with PROFILE and constraint tests.
Learn how Neo4j’s native full‑text indexes can cut query latency from seconds to milliseconds, what trade‑offs to watch for, and a step‑by‑step example that shows how to create, query, and monitor a full‑text index in a graph of millions of nodes.
Cypher's variable-length path patterns answer 'what's connected within N hops' in one line — but the hop bound and relationship-type filter are what stand between a fast query and a full-graph scan.
