Why teams connect Neo4j and RavenDB

Keep Neo4j and RavenDB synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between Neo4j and RavenDB continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • Mirror CRM accounts and contacts into a graph to model buying-group and referral relationships.
  • Sync product catalog and order history into Neo4j to power recommendation queries.
  • Stream RavenDB document changes into Postgres or a warehouse via data subscriptions for SQL analytics.
  • Sync operational documents such as orders and profiles between RavenDB and a CRM so business teams see application data.

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

What you can sync between Neo4j and RavenDB

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.

Neo4j objects RavenDB objects
Properties Key-value attributes on both nodes and relationships, mapped from source fields. Collections Groupings of documents by type, mapped to tables in relational targets
Labels Node type markers used to map source tables or objects onto the graph. Indexes Static and auto indexes used to query documents for filtered reads
Indexes & Constraints Uniqueness constraints and indexes that make MERGE-based upserts reliable and fast. Attachments Binary payloads stored with documents, handled separately from the JSON body
Databases Named databases in a single instance that scope multi-tenant or multi-domain syncs. Revisions Historical versions of documents, useful for audit-oriented replication
Users & Roles Security principals controlling what an integration credential can query or modify. Counters Numeric values attached to documents that change independently of the document body
Nodes Entity records (customers, products, accounts) written from source systems as labeled nodes. Time series Timestamped measurements stored per document, synced for metrics analysis

How the Neo4j and RavenDB connectors work

Neo4j

Integration surface
Bolt binary protocol with Cypher via official drivers, plus an HTTP query API
Authentication
Username/password (basic auth); enterprise deployments add SSO options
Change detection
Neo4j Change Data Capture on Enterprise and Aura streams graph changes; otherwise Cypher polling on timestamp properties
Capabilities
read · write · CDC

RavenDB

Integration surface
HTTP REST API with official clients (.NET, Java, Node.js, Python, and others)
Authentication
X.509 client certificates on secured servers, instead of username and password
Change detection
data subscriptions and the Changes API provide server-pushed change feeds
Capabilities
