Why teams connect Couchbase and Scaleway Postgres
Keep Couchbase and Scaleway Postgres 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 Scaleway Postgres 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
- Two-way sync between Couchbase (serving application data) and a CRM so support and sales teams see live application state.
- Consolidate documents from multiple Couchbase clusters into a single analytical store.
- Run a two-way sync between Scaleway Postgres and SaaS tools so edits made in either system converge on the same rows
- Replicate the application database into a warehouse for analytics without writing custom pipelines
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 Scaleway Postgres, 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 Couchbase and Scaleway Postgres
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 | Scaleway Postgres objects | |
|---|---|---|
| Scopes Namespaces inside a bucket used to group collections, similar to schemas. | Tables Primary sync unit; each table maps to an object or table on the other side of the sync. | |
| Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables. | Views Read-only sources for shaping data before it leaves the database. | |
| JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs. | Materialized views Precomputed result sets that can be read on a schedule for downstream syncs. | |
| Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient. | Schemas Namespace tables so multiple applications or environments can be synced selectively. | |
| XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster. | Sequences Generate primary keys; sync tooling must respect them when writing rows. | |
| Full-text search indexes Search indexes over documents, relevant when syncing searchable content. | Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system. |

How the Couchbase and Scaleway Postgres 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
Scaleway Postgres
- Integration surface
- SQL wire protocol (PostgreSQL)
- Authentication
- Database credentials (username/password over TLS)
- Change detection
- Log-based CDC via PostgreSQL logical replication where the managed instance permits it; otherwise timestamp or query-based polling

FAQ
Couchbase and Scaleway Postgres integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Couchbase and Scaleway Postgres: authenticate both systems, choose the objects to sync (such as Couchbase's Scopes and Collections), 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 Couchbase and Scaleway Postgres: Regional or environment copies; Cross-engine sync; Migration with zero-downtime cutover. Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.
-
Couchbase: SQL++ (N1QL) query service, key-value SDK APIs, and REST management APIs. Authentication: Database credentials with role-based access control, typically over TLS. Scaleway Postgres: SQL wire protocol (PostgreSQL). Authentication: Database credentials (username/password over TLS). Stacksync manages authentication, retries, and rate limits on both sides.
-
Couchbase: The Database Change Protocol (DCP) exposes an ordered stream of document mutations, and it is the same mechanism Couchbase's own XDCR replication and Kafka connector consume. Scaleway Postgres: It runs the standard PostgreSQL engine, so ordinary Postgres drivers, ORMs, and SQL tooling work unmodified; managed-service restrictions apply to some server-level features. Stacksync's field mapping accounts for these differences between Couchbase and Scaleway Postgres 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 Couchbase and Scaleway Postgres records are not retained after a sync operation.
