Why teams connect DuckDB and Körber WMS

Give your engineers Körber WMS's data in DuckDB: read it with normal queries, write back through the sync, and skip the ERP API entirely.

ERP data sits behind interfaces built for the ERP's own modules, not for your internal systems. Teams that need those records, for reporting services, internal tools, or automations, end up writing integration code against a strict API and maintaining it through every upgrade.

Stacksync mirrors Inventory, Receipts / ASNs, Orders, Shipments from Körber WMS into DuckDB and keeps both sides consistent in real time. Whatever Körber WMS is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in DuckDB sync back into Körber WMS with its validations respected.

Common use cases

  • Use DuckDB as a transform step: read synced Parquet exports, aggregate with SQL, and write results back to an operational database.
  • Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.
  • Mirror receiving and ASN data into procurement systems for inbound visibility
  • Consolidate warehouse task and throughput data into a BI warehouse for operations reporting

Where Körber WMS is the HR system of record: people data for internal systems

Worker and org records stay current in DuckDB for provisioning, access, and reporting systems that read from the database.

Controlled write-back

Choose exactly which tables and fields may flow from DuckDB back into Körber WMS, keeping the ERP authoritative.

Read ERP records with a query

Records from Körber WMS live in DuckDB as ordinary tables or collections, joinable with the rest of your data.

What you can sync between DuckDB and Körber WMS

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.

DuckDB objects Körber WMS objects
Tables Columnar tables created via SQL; the destination for materialized sync data. Items Item definitions keep the WMS aligned with the ERP item master.
Views SQL views used to shape or filter data for downstream consumers. Inventory On-hand quantities by location feed availability in order-taking systems.
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Receipts / ASNs Inbound notices and receipt confirmations sync with procurement systems.
Attached databases Additional database files or external systems attached into one session for cross-source queries. Orders Outbound orders arrive from the ERP or OMS for allocation and fulfillment.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Shipments Ship confirmations and tracking references return to the order source system.
Schemas Namespaces within a database used to organize tables in sync outputs. Locations Bin and zone definitions scope inventory data during mapping.

How the DuckDB and Körber WMS connectors work

DuckDB

Integration surface
In-process SQL engine via client libraries (Python, Node.js, JDBC, CLI); no server or network API by default
Authentication
None built in; access control is file-system level (MotherDuck adds token auth for its hosted service)
Change detection
Polling or full re-reads; no change feed or transaction log API
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by local compute and I/O

Körber WMS

Integration surface
Varies by deployment; typically host-interface messages, file exchange, or vendor APIs via middleware
Authentication
Credentials issued per deployment
Change detection
Polling or message/file-based export from the WMS host interface
Capabilities
read · write
Rate limits
Constrained by deployment architecture rather than published API rate limits
