Why teams connect MotherDuck and SingleStore

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

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

Common use cases

  • Share curated, synced datasets with other teams through read-only database shares
  • Land CRM and operational database records in MotherDuck so a small team gets warehouse-style analytics without cluster management
  • Feed synced operational data into applications that need low-latency responses over fresh data.
  • Mirror CRM and SaaS objects into SingleStore tables to serve low-latency operational dashboards.

Offload heavy reads

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

Operational data in the warehouse, minus the pipeline

Rows from SingleStore 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 SingleStore, where whatever reads from that database gets them without querying the warehouse.

What you can sync between MotherDuck and SingleStore

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.

MotherDuck objects SingleStore objects
Views Modeled projections used as outbound sync sources. Indexes and Shard Keys Determine data distribution and lookup speed for sync match keys.
Database Shares Read-only copies of a database shared with other users or teams. Databases The connection target containing the tables a sync addresses.
Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries. Tables (rowstore and columnstore) Primary read/write target; storage type affects whether a table suits point lookups or scans.
Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes. Views Read-only projections used as curated sync sources.
Schemas Namespaces within a database used to organize synced tables. Reference Tables Small tables replicated to every node, often used for dimension data in syncs.
Tables The main landing target for synced records and source for analysis. Pipelines Native ingestion jobs from Kafka or object storage that coexist with external syncs.
