Why teams connect Apache Doris and OCI Database (Oracle Cloud)

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

Common use cases

  • 01 Consolidate event and transactional data from multiple sources into one real-time OLAP layer.
  • 02 Land CRM and operational database records in Doris for low-latency dashboards over fresh data.
  • 03 Write changes from SaaS applications back into OCI so PL/SQL-based processes operate on current data.
  • 04 Replicate operational tables from OCI to an analytics warehouse with log-based CDC instead of nightly batch dumps.

Common sync patterns

Serve warehouse results at database speed

Aggregates or model outputs computed in Apache Doris 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 Apache Doris and keep OCI Database (Oracle Cloud) focused on its operational workload.

What you can sync between Apache Doris 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.

Apache Doris objects OCI Database (Oracle Cloud) objects How this pairing syncs
Tables Columnar tables in one of Doris's table models, used as sync destinations. 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.
Partitions Range or list partitions that bound incremental loads. Partitions Physical table subdivisions relevant when replicating large fact tables Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Materialized Views Precomputed views readable for downstream syncs and BI. Materialized views Precomputed result sets sometimes used as stable read sources for replication Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Databases Logical containers that scope connections and grants. Views Read-only projections used to expose curated subsets to downstream systems Databases is specific to Apache Doris and Views to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.
Unique Key Tables Tables supporting primary-key upserts, the natural target for row-level syncs. Schemas Namespace boundaries that scope which objects a sync connection can access Unique Key Tables is specific to Apache Doris and Schemas to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.
Aggregate Key Tables Tables that pre-aggregate on load, used for metric rollups. Sequences Key generators that matter when writing new rows from external systems Aggregate Key Tables is specific to Apache Doris and Sequences to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.

How changes propagate between Apache Doris 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.

Apache Doris OCI Database (Oracle Cloud) Interval-based propagation

DetectionStacksync polls Apache Doris for changes on an incremental schedule, reading only records changed since the previous pass. Polling on partition or timestamp columns for reads.

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) Apache Doris 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 Apache Doris as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Apache Doris: No API quotas; load throughput depends on cluster resources and load-job configuration.
  • OCI Database (Oracle Cloud): Throughput bounded by instance sizing rather than API quotas.
