Why teams connect MariaDB and RavenDB
Keep MariaDB 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 MariaDB 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
- 01 Feed a warehouse continuously from MariaDB using binlog-based capture instead of scheduled dumps
- 02 Keep several MariaDB instances aligned with one system of record across environments
- 03 Sync operational documents such as orders and profiles between RavenDB and a CRM so business teams see application data.
- 04 Mirror reference data from relational systems into RavenDB collections that serve application reads.
Common sync patterns
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.
Cross-engine sync
Keep the same dataset live in both MariaDB and RavenDB, so each workload runs on the engine that suits it.
What you can sync between MariaDB 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.
| MariaDB objects | RavenDB objects | How this pairing syncs | |
|---|---|---|---|
| Stored Procedures Server-side logic that can post-process synced rows. | Attachments Binary payloads stored with documents, handled separately from the JSON body | Stored Procedures is specific to MariaDB and Attachments to RavenDB — each maps to any object or custom field on the other side. | |
| Databases (Schemas) Top-level namespaces that scope a sync's reads and writes. | Revisions Historical versions of documents, useful for audit-oriented replication | Databases (Schemas) is specific to MariaDB and Revisions to RavenDB — each maps to any object or custom field on the other side. | |
| Tables The primary sync target; rows map to records in connected systems. | Counters Numeric values attached to documents that change independently of the document body | Tables is specific to MariaDB and Counters to RavenDB — each maps to any object or custom field on the other side. | |
| Views Read-side projections used as outbound sync sources. | Time series Timestamped measurements stored per document, synced for metrics analysis | Views is specific to MariaDB and Time series to RavenDB — each maps to any object or custom field on the other side. | |
| Columns Field-level mapping targets with engine-typed values. | Data subscriptions Server-side change feeds that push matching documents to consumers | Columns is specific to MariaDB and Data subscriptions to RavenDB — each maps to any object or custom field on the other side. | |
| Primary and Unique Keys Match keys for idempotent upserts. | Documents JSON records, the primary unit read and written during sync | Primary and Unique Keys is specific to MariaDB and Documents to RavenDB — each maps to any object or custom field on the other side. |
How changes propagate between MariaDB and RavenDB
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
MariaDB RavenDB Sub-second propagation
DetectionChanges in MariaDB are captured at the source via change data capture — no polling loop against its API. Database triggers — Stacksync creates deterministic triggers for internal logging and syncing.
DeliveryEach detected change is written to RavenDB through its API, with automatic retries and rate-limit backoff.
RavenDB MariaDB Sub-second propagation
DetectionChanges in RavenDB are captured at the source via change data capture — no polling loop against its API. Data subscriptions and the Changes API provide server-pushed change feeds.
DeliveryEach detected change is applied to MariaDB as a row-level write, with types converted between the two schemas.
Rate-limit considerations
- MariaDB: No API rate limits; throughput is bounded by connection limits and server resources.
- RavenDB: Throughput bounded by cluster resources rather than API quotas.

FAQ
MariaDB and RavenDB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between MariaDB and RavenDB: authenticate both systems, choose the objects to sync (such as MariaDB's Stored Procedures and Databases (Schemas)), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
MariaDB: SQL wire protocol (MySQL-compatible client/server protocol). Authentication: Database credentials (connection string or parameters), with optional SSL root certificate upload and optional SSH tunnel (SSH user + host). 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.
-
MariaDB: Tables without an auto-generated single primary key cannot be synced. RavenDB: Secured RavenDB servers authenticate clients with X.509 certificates rather than passwords, so connection setup involves certificate management. Stacksync's field mapping accounts for these differences between MariaDB 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 MariaDB and RavenDB records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed MariaDB and RavenDB connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom MariaDB–RavenDB integration in-house.
-
Yes — Stacksync ships production-grade connectors for both MariaDB and RavenDB. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
