Why teams connect MongoDB and RavenDB
Keep MongoDB 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 MongoDB 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
- Replicate operational MongoDB data into a relational database, flattening nested documents into normalized tables for SQL reporting.
- Capture change stream events and propagate them to SaaS tools in near real time instead of running batch exports.
- 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.
Regional or environment copies
Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.
Cross-engine sync
Keep the same dataset live in both MongoDB and RavenDB, so each workload runs on the engine that suits it.
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.
What you can sync between MongoDB 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.
| MongoDB objects | RavenDB objects | |
|---|---|---|
| Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets. | Counters Numeric values attached to documents that change independently of the document body | |
| Indexes Keep lookups by sync key fast on large collections. | Time series Timestamped measurements stored per document, synced for metrics analysis | |
| Views Read-only aggregation-defined sources for filtered sync datasets. | Data subscriptions Server-side change feeds that push matching documents to consumers | |
| Change streams The oplog-backed event feed that powers real-time change capture. | Documents JSON records, the primary unit read and written during sync | |
| GridFS files Chunked file storage whose metadata can be referenced by synced documents. | Collections Groupings of documents by type, mapped to tables in relational targets | |
| Databases Logical groupings of collections that scope a sync connection. | Indexes Static and auto indexes used to query documents for filtered reads |

How the MongoDB and RavenDB connectors work
MongoDB
- Integration surface
- MongoDB wire protocol via official drivers; Atlas additionally offers an administration REST API for cluster management
- Authentication
- Database credentials (username/password) or TLS/SSL X.509 certificate (.pem upload), entered individually or via a MongoDB connection string (SRV or standard); Stacksync IP allowlisting required
- Change detection
- MongoDB oplog and change streams (requires the database to run as a replica set — even single-node); Stacksync leverages these built-in tools to track changes in real time
- 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
- read · write · CDC
- Rate limits
- throughput bounded by cluster resources rather than API quotas
How it works
How to connect MongoDB to RavenDB — three steps, no code
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
- 01
Connect your apps
Authenticate MongoDB and RavenDB with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.

FAQ
MongoDB and RavenDB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between MongoDB and RavenDB: authenticate both systems, choose the objects to sync (such as MongoDB's Embedded documents and arrays and Indexes), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
MongoDB: MongoDB wire protocol via official drivers; Atlas additionally offers an administration REST API for cluster management. Authentication: Database credentials (username/password) or TLS/SSL X.509 certificate (.pem upload), entered individually or via a MongoDB connection string (SRV or standard); Stacksync IP allowlisting required. RavenDB: 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. Stacksync manages authentication, retries, and rate limits on both sides.
-
MongoDB: Change streams expose ordered change events with resume tokens, so an interrupted sync can pick up exactly where it stopped without a full re-read. RavenDB: RavenDB supports ACID transactions spanning multiple documents, which is uncommon among document databases. Stacksync's field mapping accounts for these differences between MongoDB and RavenDB without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means MongoDB and RavenDB records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed MongoDB and RavenDB connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom MongoDB–RavenDB integration in-house.
-
Yes — Stacksync ships production-grade connectors for both MongoDB and RavenDB. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
