Why teams connect InterSystems IRIS and MotherDuck

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

Stacksync covers both directions with one connection. Tables or collections in InterSystems IRIS sync into MotherDuck in real time, and result tables in MotherDuck sync back into InterSystems IRIS, 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
  • Write enriched or corrected records from SaaS apps back into IRIS tables for on-platform processing
  • Replicate IRIS tables to Postgres so application teams can build against a familiar database

Operational data in the warehouse, minus the pipeline

Rows from InterSystems IRIS 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 InterSystems IRIS, 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.

What you can sync between InterSystems IRIS 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.

InterSystems IRIS objects MotherDuck objects
Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. Schemas Namespaces within a database used to organize synced tables.
Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. Tables The main landing target for synced records and source for analysis.
Namespaces Namespaces partition databases and determine the connection context for integrations. Views Modeled projections used as outbound sync sources.
Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. Database Shares Read-only copies of a database shared with other users or teams.
Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries.
Views SQL views expose curated slices of data for outbound replication. Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes.
