Why teams connect CockroachDB and OCI Database (Oracle Cloud)

Keep CockroachDB 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 CockroachDB 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 Use changefeeds to propagate row changes from a multi-region cluster into a warehouse or search index.
  • 02 Keep reference data consistent between CockroachDB and regional application databases.
  • 03 Replicate operational tables from OCI to an analytics warehouse with log-based CDC instead of nightly batch dumps.
  • 04 Run on-prem Oracle and OCI side by side during a cloud migration while keeping both ends writable.

Common sync patterns

Cross-engine sync

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

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

Shared reference data between services

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

What you can sync between CockroachDB 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.

CockroachDB objects OCI Database (Oracle Cloud) objects How this pairing syncs
Schemas Namespaces within a database used to isolate synced tables from application tables. Schemas Namespace boundaries that scope which objects a sync connection can access Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables The core read/write target; rows sync bi-directionally with SaaS objects or other databases. 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.
Views Read-only projections used as curated sync sources. Views Read-only projections used to expose curated subsets to downstream systems Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Sequences ID generators that matter when writes originate from an external system. Sequences Key generators that matter when writing new rows from external systems Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Changefeeds Built-in CDC streams that emit row-level changes to external sinks. PL/SQL procedures and packages Server-side logic that can react to synced data or transform it in place Changefeeds is specific to CockroachDB and PL/SQL procedures and packages to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.
Databases Logical containers a sync connects to, addressed like PostgreSQL databases. JSON collections Document-style storage in the converged engine, synced alongside relational tables Databases is specific to CockroachDB and JSON collections to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.

How changes propagate between CockroachDB 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.

CockroachDB OCI Database (Oracle Cloud) Sub-second propagation

DetectionChanges in CockroachDB are captured at the source via change data capture — no polling loop against its API. CDC via changefeeds, which stream row-level changes.

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

Rate-limit considerations

  • CockroachDB: No API rate limits in the SaaS sense; throughput is bounded by cluster capacity.
  • OCI Database (Oracle Cloud): Throughput bounded by instance sizing rather than API quotas.
