Why teams connect OCI Database (Oracle Cloud) and VoltDB

Keep OCI Database (Oracle Cloud) and VoltDB 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 VoltDB 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 Run on-prem Oracle and OCI side by side during a cloud migration while keeping both ends writable.
  • 02 Expose ERP or billing data held in OCI to internal tools by syncing selected schemas to a managed Postgres.
  • 03 Keep product, plan, or entitlement state consistent between VoltDB and back-office systems.
  • 04 Push aggregates from VoltDB materialized views into dashboards or operational tools.

Common sync patterns

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 VoltDB, 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 VoltDB

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 VoltDB objects How this pairing syncs
Materialized views Precomputed result sets sometimes used as stable read sources for replication Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables The primary sync surface; rows are read and written directly over SQL Streams Insert-only constructs that feed the export subsystem with committed rows. Tables is specific to OCI Database (Oracle Cloud) and Streams to VoltDB — each maps to any object or custom field on the other side.
Views Read-only projections used to expose curated subsets to downstream systems Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks. Views is specific to OCI Database (Oracle Cloud) and Export Targets and Topics to VoltDB — each maps to any object or custom field on the other side.
Schemas Namespace boundaries that scope which objects a sync connection can access Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target. Schemas is specific to OCI Database (Oracle Cloud) and Partitioned Tables to VoltDB — each maps to any object or custom field on the other side.
Sequences Key generators that matter when writing new rows from external systems Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data. Sequences is specific to OCI Database (Oracle Cloud) and Replicated Tables to VoltDB — each maps to any object or custom field on the other side.
PL/SQL procedures and packages Server-side logic that can react to synced data or transform it in place Stored Procedures Precompiled transactional units that serve as the primary write interface. PL/SQL procedures and packages is specific to OCI Database (Oracle Cloud) and Stored Procedures to VoltDB — each maps to any object or custom field on the other side.

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

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

VoltDB OCI Database (Oracle Cloud) Interval-based propagation

DetectionStacksync polls VoltDB for changes on an incremental schedule, reading only records changed since the previous pass. Export streams and topics push committed changes to configured targets.

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.
  • VoltDB: No API rate limits; throughput is bounded by partition count and cluster sizing.
