Why teams connect MotherDuck and Neo4j

Connect Neo4j and MotherDuck with one live, two-way sync: operational rows flow into the warehouse, and computed results flow back where systems can read them fast.

Operational databases and analytical warehouses want the same data at different moments. Analysts want Neo4j's rows in MotherDuck, current and joinable, without a change-data-capture pipeline to maintain. Engineers want the outputs of warehouse work, such as aggregates, features, and segments, available in Neo4j where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in Neo4j sync into MotherDuck in real time, and result tables in MotherDuck sync back into Neo4j, with schema and type mapping between the two systems handled for you.

Common use cases

  • Land CRM and operational database records in MotherDuck so a small team gets warehouse-style analytics without cluster management
  • Sync modeled MotherDuck tables outward to operational tools for activation
  • Feed identity and access data into a graph for entitlement and blast-radius analysis.
  • Write computed relationship scores (fraud, influence, similarity) back to operational systems.

Fresh analytics without loading windows

Because changes stream continuously, analysts query current data instead of waiting for last night's load.

Offload heavy reads

Point analytical queries at the synced copy in MotherDuck and keep Neo4j focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from Neo4j land in MotherDuck as they change, replacing hand-built CDC and batch extract jobs.

What you can sync between MotherDuck and Neo4j

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

MotherDuck objects Neo4j objects
Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries. Nodes Entity records (customers, products, accounts) written from source systems as labeled nodes.
Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes. Relationships Typed, directed edges that carry the connections syncs exist to model.
Schemas Namespaces within a database used to organize synced tables. Properties Key-value attributes on both nodes and relationships, mapped from source fields.
Tables The main landing target for synced records and source for analysis. Labels Node type markers used to map source tables or objects onto the graph.
Views Modeled projections used as outbound sync sources. Indexes & Constraints Uniqueness constraints and indexes that make MERGE-based upserts reliable and fast.
Database Shares Read-only copies of a database shared with other users or teams. Databases Named databases in a single instance that scope multi-tenant or multi-domain syncs.
