Why teams connect Scaleway Postgres and VoltDB
Keep Scaleway Postgres 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 Scaleway Postgres 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
- Replicate the application database into a warehouse for analytics without writing custom pipelines
- Back internal tools with the same Postgres instance while Stacksync keeps it consistent with external systems
- Keep product, plan, or entitlement state consistent between VoltDB and back-office systems.
- Push aggregates from VoltDB materialized views into dashboards or operational tools.
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 Scaleway Postgres 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.
| Scaleway Postgres objects | VoltDB objects | |
|---|---|---|
| Materialized views Precomputed result sets that can be read on a schedule for downstream syncs. | Streams Insert-only constructs that feed the export subsystem with committed rows. | |
| Schemas Namespace tables so multiple applications or environments can be synced selectively. | Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks. | |
| Sequences Generate primary keys; sync tooling must respect them when writing rows. | Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target. | |
| Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system. | Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data. | |
| Tables Primary sync unit; each table maps to an object or table on the other side of the sync. | Stored Procedures Precompiled transactional units that serve as the primary write interface. | |
| Views Read-only sources for shaping data before it leaves the database. | Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources. |

FAQ
Scaleway Postgres and VoltDB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Scaleway Postgres and VoltDB: authenticate both systems, choose the objects to sync (such as Scaleway Postgres's Materialized views and Schemas), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Scaleway Postgres and VoltDB: Migration with zero-downtime cutover; Shared reference data between services; Regional or environment copies. When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.
-
Scaleway Postgres: SQL wire protocol (PostgreSQL). Authentication: Database credentials (username/password over TLS). VoltDB: SQL over JDBC plus native client libraries and an HTTP/JSON interface. Authentication: Database credentials. Stacksync manages authentication, retries, and rate limits on both sides.
-
Scaleway Postgres: Postgres-native types such as JSONB and arrays are available, and a sync layer must map them onto flat SaaS field types. VoltDB: The built-in export subsystem streams committed rows to external targets such as Kafka, which is the product's native change-propagation path. Stacksync's field mapping accounts for these differences between Scaleway Postgres and VoltDB without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Scaleway Postgres and VoltDB records are not retained after a sync operation.
