Why teams connect OCI Database (Oracle Cloud) and Snowflake

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

Common use cases

  • 01 Activate modeled Snowflake tables by syncing scores and attributes back into CRM fields sales can act on
  • 02 Keep a customer 360 table aligned with its source systems in both directions instead of one-way reverse ETL
  • 03 Expose ERP or billing data held in OCI to internal tools by syncing selected schemas to a managed Postgres.
  • 04 Write changes from SaaS applications back into OCI so PL/SQL-based processes operate on current data.

Common sync patterns

Serve warehouse results at database speed

Aggregates or model outputs computed in Snowflake sync into OCI Database (Oracle Cloud), 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 Snowflake and keep OCI Database (Oracle Cloud) focused on its operational workload.

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

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.

OCI Database (Oracle Cloud) objects Snowflake objects How this pairing syncs
Tables The primary sync surface; rows are read and written directly over SQL Tables The main landing and activation target for synced records. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Read-only projections used to expose curated subsets to downstream systems Views Modeled projections used as the source side of outbound syncs. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Materialized views Precomputed result sets sometimes used as stable read sources for replication Materialized Views Precomputed results synced outward for low-latency reads. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Schemas Namespace boundaries that scope which objects a sync connection can access Schemas Namespaces within a database used to organize synced tables. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Sequences Key generators that matter when writing new rows from external systems Stages File staging areas used for bulk loads into synced tables. Sequences is specific to OCI Database (Oracle Cloud) and Stages to Snowflake — each maps to any object or custom field on the other side.
PL/SQL procedures and packages Server-side logic that can react to synced data or transform it in place Tasks Scheduled SQL used to transform synced data after it lands. PL/SQL procedures and packages is specific to OCI Database (Oracle Cloud) and Tasks to Snowflake — each maps to any object or custom field on the other side.

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

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.

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

Snowflake OCI Database (Oracle Cloud) Sub-second propagation

DetectionChanges in Snowflake are captured at the source via change data capture — no polling loop against its API. The setup script grants "create stream" on synced schemas (Snowflake streams), but the docs do not name the change-capture mechanism.

DeliveryEach detected change is applied to OCI Database (Oracle Cloud) as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • OCI Database (Oracle Cloud): Throughput bounded by instance sizing rather than API quotas.
  • Snowflake: No conventional API rate limits; cost and throughput are governed by virtual warehouse size and running time.
