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

  • Land CRM and operational database records in MotherDuck so a small team gets warehouse-style analytics without cluster management
  • Sync modeled MotherDuck tables outward to operational tools for activation
  • Run on-prem Oracle and OCI side by side during a cloud migration while keeping both ends writable.
  • Expose ERP or billing data held in OCI to internal tools by syncing selected schemas to a managed Postgres.

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
Schemas Namespaces within a database used to organize synced tables. Partitions Physical table subdivisions relevant when replicating large fact tables
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
Views Modeled projections used as outbound sync sources. Views Read-only projections used to expose curated subsets to downstream systems
Database Shares Read-only copies of a database shared with other users or teams. Materialized views Precomputed result sets sometimes used as stable read sources for replication
Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries. Schemas Namespace boundaries that scope which objects a sync connection can access
Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes. Sequences Key generators that matter when writing new rows from external systems

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
MotherDuck setup guide

OCI Database (Oracle Cloud)

Integration surface
SQL wire protocol (Oracle Net) via JDBC, ODBC, and native drivers; ORDS REST optionally exposes tables over HTTP
Authentication
database credentials, commonly with mutual TLS using a client wallet on Autonomous Database; OCI IAM integration available
Change detection
log-based CDC from redo logs (LogMiner or GoldenGate), or timestamp polling
Capabilities
read · write · CDC
Rate limits
throughput bounded by instance sizing rather than API quotas
