Why teams connect Scaleway Postgres and Snowflake

Connect Scaleway Postgres and Snowflake with one live, two-way sync: operational rows flow into the warehouse, and computed results flow back where systems can read them fast.

Operational databases and analytical warehouses want the same data at different moments. Analysts want Scaleway Postgres's rows in Snowflake, current and joinable, without a change-data-capture pipeline to maintain. Engineers want the outputs of warehouse work, such as aggregates, features, and segments, available in Scaleway Postgres where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in Scaleway Postgres sync into Snowflake in real time, and result tables in Snowflake sync back into Scaleway Postgres, with schema and type mapping between the two systems handled for you.

Common use cases

  • Keep a customer 360 table aligned with its source systems in both directions instead of one-way reverse ETL
  • Push product usage aggregates from Snowflake into sales and success tools for account prioritization
  • 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

Offload heavy reads

Point analytical queries at the synced copy in Snowflake and keep Scaleway Postgres focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from Scaleway Postgres land in Snowflake as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in Snowflake sync into Scaleway Postgres, where whatever reads from that database gets them without querying the warehouse.

What you can sync between Scaleway Postgres and Snowflake

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 Snowflake objects
Schemas Namespace tables so multiple applications or environments can be synced selectively. Tables The main landing and activation target for synced records.
Sequences Generate primary keys; sync tooling must respect them when writing rows. Views Modeled projections used as the source side of outbound syncs.
Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system. Materialized Views Precomputed results synced outward for low-latency reads.
Tables Primary sync unit; each table maps to an object or table on the other side of the sync. Streams Row-level change records on a table, consumed to process deltas instead of full scans.
Views Read-only sources for shaping data before it leaves the database. Stages File staging areas used for bulk loads into synced tables.
Materialized views Precomputed result sets that can be read on a schedule for downstream syncs. Tasks Scheduled SQL used to transform synced data after it lands.

How the Scaleway Postgres and Snowflake connectors work

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
Capabilities
read · write · CDC
Rate limits
Throughput is bounded by instance size and connection limits rather than API quotas

Snowflake

Integration surface
SQL via JDBC/ODBC and native drivers, plus the Snowflake SQL REST API
Authentication
Dedicated Snowflake service user + role with RSA key-pair authentication (Stacksync-provided public key), created via a setup script requiring SECURITY_ADMIN and ACCOUNTADMIN roles
Change detection
Not explicitly stated; the setup script grants "create stream" on synced schemas (Snowflake streams), but the docs do not name the change-capture mechanism
Capabilities
read · write · CDC
Rate limits
No conventional API rate limits; cost and throughput are governed by virtual warehouse size and running time
