Why teams connect CockroachDB and MotherDuck

Connect CockroachDB 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 CockroachDB'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 CockroachDB where the services that read from it get them at normal query latency.

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

Common use cases

  • Land CRM and operational database records in MotherDuck so a small team gets warehouse-style analytics without cluster management
  • Sync modeled MotherDuck tables outward to operational tools for activation
  • Keep reference data consistent between CockroachDB and regional application databases.
  • Consolidate data from several SaaS tools into one distributed SQL store that survives zone failures.

Serve warehouse results at database speed

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

Fresh analytics without loading windows

Because changes stream continuously, analysts query current data instead of waiting for last night's load.

Offload heavy reads

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

What you can sync between CockroachDB 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.

CockroachDB objects MotherDuck objects
Tables The core read/write target; rows sync bi-directionally with SaaS objects or other databases. Schemas Namespaces within a database used to organize synced tables.
Views Read-only projections used as curated sync sources. Tables The main landing target for synced records and source for analysis.
Indexes Secondary indexes that keep sync lookup queries fast on key columns. Views Modeled projections used as outbound sync sources.
Sequences ID generators that matter when writes originate from an external system. Database Shares Read-only copies of a database shared with other users or teams.
Changefeeds Built-in CDC streams that emit row-level changes to external sinks. Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries.
Databases Logical containers a sync connects to, addressed like PostgreSQL databases. Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes.

How the CockroachDB and MotherDuck connectors work

CockroachDB

Integration surface
SQL wire protocol (PostgreSQL-compatible)
Authentication
Database credentials with TLS; client certificates or SCRAM password auth
Change detection
CDC via changefeeds, which stream row-level changes; polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits in the SaaS sense; throughput is bounded by cluster capacity

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
