Why teams connect OCI Database (Oracle Cloud) and YugabyteDB

Keep OCI Database (Oracle Cloud) and YugabyteDB 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 OCI Database (Oracle Cloud) and YugabyteDB 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 Write changes from SaaS applications back into OCI so PL/SQL-based processes operate on current data.
  • 02 Replicate operational tables from OCI to an analytics warehouse with log-based CDC instead of nightly batch dumps.
  • 03 Consolidate data from regional YugabyteDB clusters into one reporting store.
  • 04 Run log-based CDC from YugabyteDB tables into a warehouse for analytics without batch dumps.

Common sync patterns

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.

Regional or environment copies

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

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

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 YugabyteDB objects How this pairing syncs
Tables The primary sync surface; rows are read and written directly over SQL Tables Distributed SQL tables split into tablets; the primary read and write targets. 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 query results available in YSQL for read-side shaping. 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 Postgres-style namespaces in YSQL used to organize synced data. 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 Sequences ID generation objects relevant when syncing writes into YSQL tables. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
JSON collections Document-style storage in the converged engine, synced alongside relational tables Databases and Keyspaces Top-level containers for the YSQL (Postgres-style) and YCQL (Cassandra-style) APIs respectively. JSON collections is specific to OCI Database (Oracle Cloud) and Databases and Keyspaces to YugabyteDB — each maps to any object or custom field on the other side.
Partitions Physical table subdivisions relevant when replicating large fact tables Indexes Global secondary indexes maintained transactionally alongside table writes. Partitions is specific to OCI Database (Oracle Cloud) and Indexes to YugabyteDB — each maps to any object or custom field on the other side.

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

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

YugabyteDB OCI Database (Oracle Cloud) Sub-second propagation

DetectionChanges in YugabyteDB are captured at the source via change data capture — no polling loop against its API. Native CDC from the write-ahead log via PostgreSQL logical replication or Debezium-compatible connectors.

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.
  • YugabyteDB: No API rate limits; throughput scales with cluster nodes and tablet distribution.
