Why teams connect RavenDB and SQL Server
Keep RavenDB and SQL Server 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 RavenDB and SQL Server 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
- 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.
- Bi-directional sync between SQL Server rows and CRM objects so .NET line-of-business apps and sales tools share one dataset
- Expose SaaS records as SQL Server tables that existing SSRS reports and internal apps can query
Cross-engine sync
Keep the same dataset live in both RavenDB and SQL Server, 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.
Shared reference data between services
Services that own separate databases stay consistent on the records they share, without a custom replication layer.
What you can sync between RavenDB and SQL Server
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.
| RavenDB objects | SQL Server objects | |
|---|---|---|
| Documents JSON records, the primary unit read and written during sync | Columns Field-level mapping targets with T-SQL types. | |
| Collections Groupings of documents by type, mapped to tables in relational targets | Primary and Unique Keys Match keys for idempotent upserts and conflict handling. | |
| Indexes Static and auto indexes used to query documents for filtered reads | CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers. | |
| Attachments Binary payloads stored with documents, handled separately from the JSON body | Stored Procedures T-SQL logic that can validate or post-process synced rows. | |
| Revisions Historical versions of documents, useful for audit-oriented replication | Databases Instance-level databases that scope a sync's reads and writes. | |
| Counters Numeric values attached to documents that change independently of the document body | Schemas Namespaces (dbo and custom) used to organize synced tables. |

How the RavenDB and SQL Server connectors work
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
SQL Server
- Integration surface
- SQL over the TDS wire protocol (Tabular Data Stream), via ODBC/JDBC/ADO.NET drivers
- Authentication
- Database credentials entered as a connection string or as parameters (host/user/password) in the Create New Sync page
- Change detection
- SQL Server Native Change Data Capture (CDC); a DBA runs a one-time setup script with sysadmin privileges to enable CDC and create Stacksync wrapper procedures
- Capabilities
- read · write · CDC
- Rate limits
- No API rate limits; throughput depends on instance resources, licensing tier, and connection limits
How it works
How to connect RavenDB to SQL Server — 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 RavenDB and SQL Server with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.

FAQ
RavenDB and SQL Server integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between RavenDB and SQL Server: authenticate both systems, choose the objects to sync (such as RavenDB's Documents and Collections), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for RavenDB and SQL Server: Cross-engine sync; Migration with zero-downtime cutover; Shared reference data between services. Keep the same dataset live in both RavenDB and SQL Server, so each workload runs on the engine that suits it.
-
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. SQL Server: SQL over the TDS wire protocol (Tabular Data Stream), via ODBC/JDBC/ADO.NET drivers. Authentication: Database credentials entered as a connection string or as parameters (host/user/password) in the Create New Sync page. Stacksync manages authentication, retries, and rate limits on both sides.
-
RavenDB: Documents can carry attachments, revisions, counters, and time series alongside the JSON body, so a complete sync covers more than the document payload. SQL Server: Change Tracking is a lower-overhead alternative that records which rows changed, but not intermediate values, so it suits net-change syncs. Stacksync's field mapping accounts for these differences between RavenDB and SQL Server 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 RavenDB and SQL Server records are not retained after a sync operation.
