Why teams connect Couchbase and MotherDuck

Connect Couchbase and MotherDuck with one live, two-way sync: operational rows flow into the warehouse, and computed results flow back where systems can read them fast.

Operational databases and analytical warehouses want the same data at different moments. Analysts want Couchbase's rows in MotherDuck, current and joinable, without a change-data-capture pipeline to maintain. Engineers want the outputs of warehouse work, such as aggregates, features, and segments, available in Couchbase where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in Couchbase sync into MotherDuck in real time, and result tables in MotherDuck sync back into Couchbase, with schema and type mapping between the two systems handled for you.

Common use cases

  • Sync modeled MotherDuck tables outward to operational tools for activation
  • Share curated, synced datasets with other teams through read-only database shares
  • Two-way sync between Couchbase (serving application data) and a CRM so support and sales teams see live application state.
  • Consolidate documents from multiple Couchbase clusters into a single analytical store.

Offload heavy reads

Point analytical queries at the synced copy in MotherDuck and keep Couchbase focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from Couchbase land in MotherDuck as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in MotherDuck sync into Couchbase, where whatever reads from that database gets them without querying the warehouse.

What you can sync between Couchbase and MotherDuck

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 MotherDuck objects
Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas. Schemas Namespaces within a database used to organize synced tables.
Scopes Namespaces inside a bucket used to group collections, similar to schemas. Tables The main landing target for synced records and source for analysis.
Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables. Views Modeled projections used as outbound sync sources.
JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs. Database Shares Read-only copies of a database shared with other users or teams.
Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient. Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries.
XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster. Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes.

How the Couchbase and MotherDuck 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

MotherDuck

Integration surface
SQL through DuckDB clients and drivers using a MotherDuck (md:) connection
Authentication
Access token created in MotherDuck (Settings > General > Create Token), pasted into Stacksync; database name and schema configurable if not using defaults
Change detection
Polling; no log-based CDC or webhook surface is exposed
Capabilities
read · write
Rate limits
Subject to the platform's compute and concurrency limits rather than per-request API rate limits
