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

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

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
Sequences Key generators that matter when writing new rows from external systems Tables The main landing and activation target for synced records.
PL/SQL procedures and packages Server-side logic that can react to synced data or transform it in place Views Modeled projections used as the source side of outbound syncs.
JSON collections Document-style storage in the converged engine, synced alongside relational tables Materialized Views Precomputed results synced outward for low-latency reads.
Partitions Physical table subdivisions relevant when replicating large fact tables Streams Row-level change records on a table, consumed to process deltas instead of full scans.
Tables The primary sync surface; rows are read and written directly over SQL Stages File staging areas used for bulk loads into synced tables.
Views Read-only projections used to expose curated subsets to downstream systems Tasks Scheduled SQL used to transform synced data after it lands.

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

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

Snowflake

Integration surface
SQL via JDBC/ODBC and native drivers, plus the Snowflake SQL REST API
Authentication
Dedicated Snowflake service user + role with RSA key-pair authentication (Stacksync-provided public key), created via a setup script requiring SECURITY_ADMIN and ACCOUNTADMIN roles
Change detection
Not explicitly stated; the setup script grants "create stream" on synced schemas (Snowflake streams), but the docs do not name the change-capture mechanism
Capabilities
read · write · CDC
Rate limits
No conventional API rate limits; cost and throughput are governed by virtual warehouse size and running time
