Why teams connect BigQuery and OCI Database (Oracle Cloud)

Connect OCI Database (Oracle Cloud) and BigQuery 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 BigQuery, 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 BigQuery in real time, and result tables in BigQuery sync back into OCI Database (Oracle Cloud), with schema and type mapping between the two systems handled for you.

Common use cases

  • Feed ML feature tables in BigQuery from operational systems on a continuous schedule
  • Land CRM and ERP records in BigQuery continuously so dashboards reflect business systems without nightly batch jobs
  • 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.

Offload heavy reads

Point analytical queries at the synced copy in BigQuery 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 BigQuery as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in BigQuery sync into OCI Database (Oracle Cloud), where whatever reads from that database gets them without querying the warehouse.

What you can sync between BigQuery 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.

BigQuery objects OCI Database (Oracle Cloud) objects
Partitioned tables Synced like regular tables; partition columns map to target fields. Views Read-only projections used to expose curated subsets to downstream systems
Clustered tables Supported; clustering is transparent to the sync. Materialized views Precomputed result sets sometimes used as stable read sources for replication
Datasets Organizational container — you pick which dataset’s tables to sync. Schemas Namespace boundaries that scope which objects a sync connection can access
Projects Connection scope: the service account grants access per project. Sequences Key generators that matter when writing new rows from external systems
Tables The syncable unit: only tables can be synced per the Stacksync docs. PL/SQL procedures and packages Server-side logic that can react to synced data or transform it in place

How the BigQuery and OCI Database (Oracle Cloud) connectors work

BigQuery

Integration surface
GoogleSQL via the BigQuery REST API, client libraries, JDBC/ODBC drivers, and the Storage Read/Write APIs
Authentication
Google Cloud service account: create a dedicated service account, grant roles (BigQuery Data Editor, BigQuery Job User, Cloud Functions Service Agent, Cloud Run Developer, Eventarc Event Receiver
Change detection
Real-time notification service deployed into your Google Cloud project: Eventarc ("a notification service that enables real-time updates to happen") with a Cloud Run "secure portal for real-time notification service in
Capabilities
read · write · CDC
Rate limits
Subject to Google Cloud quotas on queries, DML, and streaming; DML is supported but the platform favors append-heavy batch and streaming loads over row-at-a-time writes
BigQuery 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
