Why teams connect SAP Hana and Scaleway Postgres

Keep SAP Hana 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 SAP Hana 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

  • 01 Detect inserts, updates, and deletes on high-write tables via AFTER triggers or a last-modified column and replicate the deltas downstream near-real-time.
  • 02 Read SYS.TABLES and TABLE_COLUMNS system views to auto-discover schema and generate field mappings when new tables are added to the sync.
  • 03 Back internal tools with the same Postgres instance while Stacksync keeps it consistent with external systems
  • 04 Keep an EU-hosted Postgres as the system of record while distributing data to US-hosted SaaS applications

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 SAP Hana 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 SAP Hana 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.

SAP Hana objects Scaleway Postgres objects How this pairing syncs
Schemas Namespaces that group tables and views; the connector targets a schema and enumerates its objects from the catalog to build the sync. Schemas Namespace tables so multiple applications or environments can be synced selectively. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Sequences Server-generated key values; relevant when writing rows into tables whose identity is assigned HANA-side rather than by the source system. Sequences Generate primary keys; sync tooling must respect them when writing rows. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Triggers AFTER INSERT/UPDATE/DELETE triggers capture changes into a shadow/logging table so updates and deletes are detected near-real-time without full scans. Materialized views Precomputed result sets that can be read on a schedule for downstream syncs. Triggers is specific to SAP Hana and Materialized views to Scaleway Postgres — each maps to any object or custom field on the other side.
System-versioned temporal tables Column store tables with a history table tracking each row's validity period; used to reconstruct update and delete history for change capture. Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system. System-versioned temporal tables is specific to SAP Hana and Columns to Scaleway Postgres — each maps to any object or custom field on the other side.
System views (SYS schema) Catalog and monitoring views such as SYS.TABLES and TABLE_COLUMNS; read to discover schema and auto-generate field mappings for new tables. Tables Primary sync unit; each table maps to an object or table on the other side of the sync. System views (SYS schema) is specific to SAP Hana and Tables to Scaleway Postgres — each maps to any object or custom field on the other side.
Column store tables HANA's default table type, optimized for analytics; synced two-way as rows over the SQL interface with the primary key driving upserts and delete tracking. Views Read-only sources for shaping data before it leaves the database. Column store tables is specific to SAP Hana and Views to Scaleway Postgres — each maps to any object or custom field on the other side.

How changes propagate between SAP Hana and Scaleway Postgres

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.

SAP Hana Scaleway Postgres Sub-second propagation

DetectionChanges in SAP Hana are captured at the source via change data capture — no polling loop against its API. Polling on a last-modified timestamp column, or AFTER INSERT/UPDATE/DELETE triggers writing to a shadow table.

DeliveryEach detected change is applied to Scaleway Postgres as a row-level write, with types converted between the two schemas.

Scaleway Postgres SAP Hana Sub-second propagation

DetectionChanges in Scaleway Postgres are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication where the managed instance permits it.

DeliveryEach detected change is applied to SAP Hana as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • SAP Hana: No SaaS-style request quota; throughput is bounded by connection limits, statement memory caps, and workload-class admission control (concurrency/memory limits) that share capacity with production queries.
  • Scaleway Postgres: Throughput is bounded by instance size and connection limits rather than API quotas.

How the SAP Hana and Scaleway Postgres connectors work

SAP Hana

Integration surface
SQL over the SAP HANA client (JDBC/ODBC drivers); OData/REST via XS for app-layer access
Authentication
Dedicated database user credentials over an encrypted TLS connection (password sent hashed); Kerberos, SAML, JWT, and X.509 certificate authentication are also supported. SAP HANA Cloud enforces TLS and IP allowlisting.
Change detection
Polling on a last-modified timestamp column, or AFTER INSERT/UPDATE/DELETE triggers writing to a shadow table; system-versioned temporal tables and SLT/SDI provide trigger- and log-based CDC. No native webhooks.
