Why teams connect Apache Cassandra and OCI Database (Oracle Cloud)

Keep Apache Cassandra 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 Apache Cassandra 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

  • Replicate high-volume event or profile tables from Cassandra into a warehouse for analytics that CQL cannot express.
  • Sync customer profile data between Cassandra and a CRM so operational apps and sales tools agree.
  • 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.

Cross-engine sync

Keep the same dataset live in both Apache Cassandra 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 Apache Cassandra 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.

Apache Cassandra objects OCI Database (Oracle Cloud) objects
Partitions and Rows Records located by partition and clustering keys during reads and upserts. PL/SQL procedures and packages Server-side logic that can react to synced data or transform it in place
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. JSON collections Document-style storage in the converged engine, synced alongside relational tables
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Partitions Physical table subdivisions relevant when replicating large fact tables
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Tables The primary sync surface; rows are read and written directly over SQL
Collections List, set, and map columns handled with type-aware field mapping. Views Read-only projections used to expose curated subsets to downstream systems
Counters Increment-only counter columns, usually read-only in syncs. Materialized views Precomputed result sets sometimes used as stable read sources for replication

How the Apache Cassandra and OCI Database (Oracle Cloud) connectors work

Apache Cassandra

Integration surface
CQL over the Cassandra native binary protocol
Authentication
Database credentials (password authenticator); TLS and role-based grants where configured
Change detection
Commit-log based CDC on tables with CDC enabled, or polling using writetime metadata and timestamp columns
Capabilities
read · write · CDC
Rate limits
No API quotas; throughput is governed by cluster capacity and consistency-level choices

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
