Why teams connect IBM AS/400 and MotherDuck

Connect IBM AS/400 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 IBM AS/400'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 IBM AS/400 where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in IBM AS/400 sync into MotherDuck in real time, and result tables in MotherDuck sync back into IBM AS/400, 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
  • Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.
  • Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.

Offload heavy reads

Point analytical queries at the synced copy in MotherDuck and keep IBM AS/400 focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from IBM AS/400 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 IBM AS/400, where whatever reads from that database gets them without querying the warehouse.

What you can sync between IBM AS/400 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.

IBM AS/400 objects MotherDuck objects
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Database Shares Read-only copies of a database shared with other users or teams.
Rows / records The unit of read and write, accessed via SQL or record-level access. Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries.
Journals and journal receivers The change log that enables log-based CDC on journaled files. Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes.
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Schemas Namespaces within a database used to organize synced tables.
Libraries The schema-equivalent containers that scope which files a sync reads. Tables The main landing target for synced records and source for analysis.
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Views Modeled projections used as outbound sync sources.

How the IBM AS/400 and MotherDuck connectors work

IBM AS/400

Integration surface
SQL over JDBC/ODBC to Db2 for i (for example the JTOpen/jt400 driver), alongside native record-level access
Authentication
IBM i user profile credentials (database credentials)
Change detection
Journal-based CDC by reading journal receivers on journaled files; polling as a fallback
Capabilities
read · write · CDC
Rate limits
Bounded by system resources and subsystem configuration rather than an API quota.

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
