Why teams connect MotherDuck and SAP Hana

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

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

Common use cases

  • 01 Land CRM and operational database records in MotherDuck so a small team gets warehouse-style analytics without cluster management
  • 02 Sync modeled MotherDuck tables outward to operational tools for activation
  • 03 Detect inserts, updates, and deletes on high-write tables via AFTER triggers or a last-modified column and replicate the deltas downstream near-real-time.
  • 04 Read SYS.TABLES and TABLE_COLUMNS system views to auto-discover schema and generate field mappings when new tables are added to the sync.

Common sync patterns

Serve warehouse results at database speed

Aggregates or model outputs computed in MotherDuck sync into SAP Hana, 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 SAP Hana focused on its operational workload.

What you can sync between MotherDuck and SAP Hana

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 SAP Hana objects How this pairing syncs
Schemas Namespaces within a database used to organize synced tables. Schemas Namespaces that group tables and views; the connector targets a schema and enumerates its objects from the catalog to build the sync. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries. Sequences Server-generated key values; relevant when writing rows into tables whose identity is assigned HANA-side rather than by the source system. Attached Local DuckDB Databases is specific to MotherDuck and Sequences to SAP Hana — each maps to any object or custom field on the other side.
Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes. Triggers AFTER INSERT/UPDATE/DELETE triggers capture changes into a shadow/logging table so updates and deletes are detected near-real-time without full scans. Databases is specific to MotherDuck and Triggers to SAP Hana — each maps to any object or custom field on the other side.
Tables The main landing target for synced records and source for analysis. System-versioned temporal tables Column store tables with a history table tracking each row's validity period; used to reconstruct update and delete history for change capture. Tables is specific to MotherDuck and System-versioned temporal tables to SAP Hana — each maps to any object or custom field on the other side.
Views Modeled projections used as outbound sync sources. System views (SYS schema) Catalog and monitoring views such as SYS.TABLES and TABLE_COLUMNS; read to discover schema and auto-generate field mappings for new tables. Views is specific to MotherDuck and System views (SYS schema) to SAP Hana — each maps to any object or custom field on the other side.
Database Shares Read-only copies of a database shared with other users or teams. Column store tables HANA's default table type, optimized for analytics; synced two-way as rows over the SQL interface with the primary key driving upserts and delete tracking. Database Shares is specific to MotherDuck and Column store tables to SAP Hana — each maps to any object or custom field on the other side.

How changes propagate between MotherDuck and SAP Hana

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

MotherDuck SAP Hana Interval-based propagation

DetectionStacksync polls MotherDuck for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

DeliveryEach detected change is applied to SAP Hana as a row-level write, with types converted between the two schemas.

SAP Hana MotherDuck Sub-second propagation

DetectionChanges in SAP Hana are captured at the source via change data capture — no polling loop against its API. Polling on a last-modified timestamp column, or AFTER INSERT/UPDATE/DELETE triggers writing to a shadow table.

DeliveryEach detected change is applied to MotherDuck as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • MotherDuck: Subject to the platform's compute and concurrency limits rather than per-request API rate limits.
  • SAP Hana: No SaaS-style request quota; throughput is bounded by connection limits, statement memory caps, and workload-class admission control (concurrency/memory limits) that share capacity with production queries.
