Use MERGE to avoid duplicate nodes

To prevent duplicate nodes during graph data imports in FalkorDB, use idempotent upsert operations with the Cypher MERGE clause. MERGE ensures a node is only created if it does not already exist, keeping your graph duplicate-free.

In Cypher MERGE workflows, ON CREATE executes property updates only when a new node is generated, while ON MATCH applies conditional updates to existing records. This allows handling new and existing graph entities differently within a single query.

Perform idempotent upserts in a FalkorDB graph database by executing MERGE statements. This pattern safely creates missing nodes or updates existing ones, ensuring repeated data imports do not generate duplicate graph entities.

Yes, you can update existing user properties instead of creating duplicates in FalkorDB by combining the MERGE clause with ON MATCH. This conditionally updates existing graph entities during repeated data imports without generating duplicates.

Use MERGE instead of CREATE for node management when you need idempotent operations that prevent duplicate nodes. CREATE will generate a new node every time, whereas MERGE safely upserts data, making it ideal for maintaining duplicate-free graphs.
