Memgraph
Recommendation Engine

Recommendations start with relationships.

Customers and products are connected in ways that tabular data can't capture. Memgraph models those relationships as a graph and runs recommendations as simple queries on live data.

The problem

SQL was never built for this.

Schema changes break as habits change

Customer behavior evolves constantly. Relational schemas that work today require painful migrations tomorrow. Graph models adapt without restructuring the database.

Multi-hop recommendations require complex JOINs

"Customers who bought this also bought that" is a two-hop graph traversal. In SQL, it's a series of nested JOINs that degrade under load and become unmaintainable as the data grows.

Recommendations on stale data miss the moment

Batch-computed recommendations reflect yesterday's behavior. Graph databases run on live data so recommendations adapt to what customers are doing right now.

How Memgraph Helps

From customer behavior to accurate recommendations in real time.

Information modeling
Maximize the value of customer-product interactions

Model customers, products, and their interactions as a connected graph. Analyzing those relationships gives you insight into habits and preferences that aggregate metrics miss entirely.

Incremental build
Start simple, scale to production

Build your recommendation pipeline incrementally: from simple collaborative filtering to full graph neural network-powered recommendations. Each step runs on the same graph, no migration required.

Graph algorithms
Complex insights as simple Cypher queries

Graph neural networks, community detection, and collaborative filtering algorithms are all available as built-in MAGE procedures. Call them directly from Cypher - no complex JOINs, no custom code.

Capabilities

Why Memgraph.

Built for real-time, write-heavy recommendation workloads.

  • Performance

    In-memory architecture handles concurrent, write-heavy data at C++ speed. Recommendations that run on live data need the latency to match. Validate the numbers against your own workload with Memgraph's published benchmarks.

  • High Availability

    HA replication and automatic failover keep your recommendation graph available. Your recommendation pipeline can't have downtime windows.

  • Flexibility

    Fits your existing stack. Cypher-compatible with connectors for Kafka, Pulsar, and Redpanda. Custom procedures in Python and C/C++. Deploy on-premise or on AWS.

Why Are SQL Databases Outdated for the Real-Time Recommendation Engines

If a recommendation engine built on relational databases is falling apart due to the bottlenecks made by complex JOINs and never-ending schema changes, there is only one permanent and game-changing solution: graph databases.
