Why teams connect OCI Database (Oracle Cloud) and OpenSearch

Keep OCI Database (Oracle Cloud) and OpenSearch 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 OpenSearch 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

  • Write changes from SaaS applications back into OCI so PL/SQL-based processes operate on current data.
  • Replicate operational tables from OCI to an analytics warehouse with log-based CDC instead of nightly batch dumps.
  • Stream CRM records such as accounts, contacts, and tickets into OpenSearch to power internal search across customer data.
  • Sync product catalogs from an ERP or database into the indexes that back storefront search.

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 OCI Database (Oracle Cloud) and OpenSearch, 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.

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

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 OpenSearch objects
Views Read-only projections used to expose curated subsets to downstream systems Indexes The core container; synced records land in indexes with defined mappings
Materialized views Precomputed result sets sometimes used as stable read sources for replication Documents JSON records written via the index and bulk APIs and read via search queries
Schemas Namespace boundaries that scope which objects a sync connection can access Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills
Sequences Key generators that matter when writing new rows from external systems Index templates Mapping and settings presets applied to new indexes a sync creates
PL/SQL procedures and packages Server-side logic that can react to synced data or transform it in place Ingest pipelines Server-side processors that transform documents as they are written
JSON collections Document-style storage in the converged engine, synced alongside relational tables Data streams Append-oriented time-series storage for logs and events pushed from source systems

How the OCI Database (Oracle Cloud) and OpenSearch connectors work

OCI Database (Oracle Cloud)

Integration surface
SQL wire protocol (Oracle Net) via JDBC, ODBC, and native drivers; ORDS REST optionally exposes tables over HTTP
Authentication
database credentials, commonly with mutual TLS using a client wallet on Autonomous Database; OCI IAM integration available
Change detection
log-based CDC from redo logs (LogMiner or GoldenGate), or timestamp polling
Capabilities
read · write · CDC
Rate limits
throughput bounded by instance sizing rather than API quotas

OpenSearch

Integration surface
REST API over HTTP(S) with JSON payloads
Authentication
basic authentication with the security plugin, or AWS IAM request signing on Amazon OpenSearch Service
Change detection
no native change feed; reads rely on queries with scroll or point-in-time polling
Capabilities
read · write
Rate limits
throughput bounded by cluster sizing rather than fixed API quotas
