Why teams connect Azure Cosmos DB and OCI Database (Oracle Cloud)

Keep Azure Cosmos DB and OCI Database (Oracle Cloud) synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between Azure Cosmos DB and OCI Database (Oracle Cloud) continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • 01 Two-way sync between a Cosmos DB-backed product catalog and a PIM or commerce platform.
  • 02 Consolidate documents from multiple containers into a single reporting store.
  • 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

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

Cross-engine sync

Keep the same dataset live in both Azure Cosmos DB and OCI Database (Oracle Cloud), so each workload runs on the engine that suits it.

What you can sync between Azure Cosmos DB 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.

Azure Cosmos DB objects OCI Database (Oracle Cloud) objects How this pairing syncs
Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation. Schemas Namespace boundaries that scope which objects a sync connection can access Stored procedures and triggers is specific to Azure Cosmos DB and Schemas to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.
Databases Top-level namespaces that scope containers and throughput provisioning. Sequences Key generators that matter when writing new rows from external systems Databases is specific to Azure Cosmos DB and Sequences to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.
Containers The unit of partitioning and throughput; each container maps to a synced collection. PL/SQL procedures and packages Server-side logic that can react to synced data or transform it in place Containers is specific to Azure Cosmos DB and PL/SQL procedures and packages to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.
Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed. JSON collections Document-style storage in the converged engine, synced alongside relational tables Items (JSON documents) is specific to Azure Cosmos DB and JSON collections to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.
Partition keys Determine data distribution and must be included on writes for the sync to route items correctly. Partitions Physical table subdivisions relevant when replicating large fact tables Partition keys is specific to Azure Cosmos DB and Partitions to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.
Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync. Tables The primary sync surface; rows are read and written directly over SQL Change feed entries is specific to Azure Cosmos DB and Tables to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.

How changes propagate between Azure Cosmos DB 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.

Azure Cosmos DB OCI Database (Oracle Cloud) Sub-second propagation

DetectionChanges in Azure Cosmos DB are captured at the source via change data capture — no polling loop against its API. Built-in change feed exposing inserts and updates in order within each partition key range.

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) Azure Cosmos DB 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 Azure Cosmos DB 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.
