Why teams connect Azure SQL Database and Couchbase

Keep Azure SQL Database and Couchbase 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 Azure SQL Database and Couchbase 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 Azure SQL tables to a warehouse without building custom CDC pipelines.
  • Consolidate data from several line-of-business apps into one Azure SQL database as an integration hub.
  • Stream document mutations via DCP into downstream systems so caches, search indexes, or warehouses stay current.
  • Two-way sync between Couchbase (serving application data) and a CRM so support and sales teams see live application state.

Cross-engine sync

Keep the same dataset live in both Azure SQL Database and Couchbase, 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 Azure SQL Database and Couchbase

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.

Azure SQL Database objects Couchbase objects
Stored procedures Existing business logic that some teams invoke on write instead of direct table inserts. Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables.
Change tracking / CDC tables System-maintained change records used to drive incremental sync. JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs.
Tables The primary sync target; rows map one-to-one to records in the paired system. Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient.
Views Read-only projections used when the sync should expose a curated shape rather than raw tables. XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster.
Schemas Namespaces that organize tables and control which objects a sync user can reach. Full-text search indexes Search indexes over documents, relevant when syncing searchable content.
Rows and columns Standard relational records with typed columns; primary keys anchor upserts. Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas.

How the Azure SQL Database and Couchbase connectors work

Azure SQL Database

Integration surface
SQL wire protocol (TDS), the same protocol as SQL Server; T-SQL over standard drivers
Authentication
SQL authentication (database credentials) or Microsoft Entra ID authentication
Change detection
Change data capture or change tracking, both supported on Azure SQL Database; polling as a fallback
Capabilities
read · write · CDC

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
How it works

How to connect Azure SQL Database to Couchbase — three steps, no code
