Why teams connect Couchbase and Oracle DB

Keep Couchbase and Oracle DB 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 Couchbase and Oracle DB 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

  • Sync Couchbase JSON documents into Postgres or a warehouse where analysts work with flattened relational tables.
  • Stream document mutations via DCP into downstream systems so caches, search indexes, or warehouses stay current.
  • Keep legacy Oracle applications running while newer services read and write the same data through a synced copy.
  • Write changes from SaaS apps back into Oracle so PL/SQL jobs and reports run on current data.

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 Couchbase and Oracle DB, so each workload runs on the engine that suits it.

What you can sync between Couchbase and Oracle DB

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.

Couchbase objects Oracle DB objects
Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas. Views Curated read-only projections exposed to downstream consumers
Scopes Namespaces inside a bucket used to group collections, similar to schemas. Materialized views Precomputed results occasionally used as stable replication sources
Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables. Schemas Per-user namespaces that scope sync permissions and object visibility
JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs. Sequences Key generators to respect when external systems insert rows
Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient. PL/SQL procedures and packages In-database logic that can consume or transform synced data
XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster. Partitions Physical subdivisions relevant when replicating high-volume tables

How the Couchbase and Oracle DB connectors work

Couchbase

Integration surface
SQL++ (N1QL) query service, key-value SDK APIs, and REST management APIs
Authentication
Database credentials with role-based access control, typically over TLS
Change detection
Database Change Protocol (DCP) streams document mutations; SQL++ polling on document fields as an alternative
Capabilities
read · write · CDC
Rate limits
Throughput is bounded by cluster sizing rather than API rate limits

Oracle DB

Integration surface
SQL wire protocol (Oracle Net) via JDBC, ODBC, and native OCI drivers
Authentication
database username and password; wallets, Kerberos, and directory-based authentication in enterprise setups
Change detection
log-based CDC from redo logs via LogMiner or GoldenGate, or trigger and timestamp polling
Capabilities
read · write · CDC
Rate limits
throughput bounded by database resources rather than API quotas
How it works

How to connect Couchbase to Oracle DB — three steps, no code

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
