Why teams connect Couchbase and MariaDB
Keep Couchbase and MariaDB 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 Couchbase and MariaDB 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
- Sync Couchbase JSON documents into Postgres or a warehouse where analysts work with flattened relational tables.
- Stream document mutations via DCP into downstream systems so caches, search indexes, or warehouses stay current.
- Keep several MariaDB instances aligned with one system of record across environments
- Two-way sync between a MariaDB application database and a CRM so both systems hold the same customer records
Cross-engine sync
Keep the same dataset live in both Couchbase and MariaDB, 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 Couchbase and MariaDB
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.
| Couchbase objects | MariaDB objects | |
|---|---|---|
| Full-text search indexes Search indexes over documents, relevant when syncing searchable content. | Views Read-side projections used as outbound sync sources. | |
| Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas. | Columns Field-level mapping targets with engine-typed values. | |
| Scopes Namespaces inside a bucket used to group collections, similar to schemas. | Primary and Unique Keys Match keys for idempotent upserts. | |
| Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables. | System-Versioned Tables Temporal tables that retain row history natively, useful for auditing synced changes. | |
| JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs. | JSON Columns Semi-structured payloads validated with JSON functions. | |
| Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient. | Stored Procedures Server-side logic that can post-process synced rows. |

How the Couchbase and MariaDB connectors work
Couchbase
- Integration surface
- SQL++ (N1QL) query service, key-value SDK APIs, and REST management APIs
- Authentication
- Database credentials with role-based access control, typically over TLS
- Change detection
- Database Change Protocol (DCP) streams document mutations; SQL++ polling on document fields as an alternative
- Capabilities
- read · write · CDC
- Rate limits
- Throughput is bounded by cluster sizing rather than API rate limits
MariaDB
- Integration surface
- 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)
- Change detection
- Database triggers — Stacksync creates deterministic triggers for internal logging and syncing
- Capabilities
- read · write · CDC
- Rate limits
- No API rate limits; throughput is bounded by connection limits and server resources
How it works
How to connect Couchbase to MariaDB — 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.

FAQ
Couchbase and MariaDB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Couchbase and MariaDB: authenticate both systems, choose the objects to sync (such as Couchbase's Full-text search indexes and Buckets), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
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 Couchbase and MariaDB records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Couchbase and MariaDB connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Couchbase–MariaDB integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Couchbase and MariaDB. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Couchbase: Database Change Protocol (DCP) streams document mutations; SQL++ polling on document fields as an alternative. On MariaDB: Database triggers — Stacksync creates deterministic triggers for internal logging and syncing. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Couchbase side: Global Secondary Indexes, XDCR replications, Full-text search indexes, Buckets, plus custom fields where Couchbase exposes them. On the MariaDB side: Tables, Views, Columns, Primary and Unique Keys. Stacksync auto-detects both schemas and converts types between the two systems.
