Why teams connect MotherDuck and OCI Database (Oracle Cloud)

Connect OCI Database (Oracle Cloud) 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 OCI Database (Oracle Cloud)'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 OCI Database (Oracle Cloud) where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in OCI Database (Oracle Cloud) sync into MotherDuck in real time, and result tables in MotherDuck sync back into OCI Database (Oracle Cloud), 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 Run on-prem Oracle and OCI side by side during a cloud migration while keeping both ends writable.
  • 04 Expose ERP or billing data held in OCI to internal tools by syncing selected schemas to a managed Postgres.

Common sync patterns

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 OCI Database (Oracle Cloud) focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from OCI Database (Oracle Cloud) land in MotherDuck as they change, replacing hand-built CDC and batch extract jobs.

What you can sync between MotherDuck and OCI Database (Oracle Cloud)

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 OCI Database (Oracle Cloud) objects How this pairing syncs
Schemas Namespaces within a database used to organize synced tables. Schemas Namespace boundaries that scope which objects a sync connection can access Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables The main landing target for synced records and source for analysis. Tables The primary sync surface; rows are read and written directly over SQL Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Modeled projections used as outbound sync sources. Views Read-only projections used to expose curated subsets to downstream systems Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Database Shares Read-only copies of a database shared with other users or teams. Sequences Key generators that matter when writing new rows from external systems Database Shares is specific to MotherDuck and Sequences to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.
Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries. PL/SQL procedures and packages Server-side logic that can react to synced data or transform it in place Attached Local DuckDB Databases is specific to MotherDuck and PL/SQL procedures and packages to OCI Database (Oracle Cloud) — 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. JSON collections Document-style storage in the converged engine, synced alongside relational tables Databases is specific to MotherDuck and JSON collections to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.

How changes propagate between MotherDuck and OCI Database (Oracle Cloud)

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 OCI Database (Oracle Cloud) 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 OCI Database (Oracle Cloud) as a row-level write, with types converted between the two schemas.

OCI Database (Oracle Cloud) MotherDuck Sub-second propagation

DetectionChanges in OCI Database (Oracle Cloud) are captured at the source via change data capture — no polling loop against its API. Log-based CDC from redo logs (LogMiner or GoldenGate), or timestamp polling.

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.
  • OCI Database (Oracle Cloud): Throughput bounded by instance sizing rather than API quotas.
