Why teams connect Google AlloyDB and Snowflake

Connect Google AlloyDB 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 Google AlloyDB'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 Google AlloyDB where the services that read from it get them at normal query latency.

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

Common use cases

  • Feed finance reconciliation models from ERP data landed in Snowflake on a continuous basis
  • Land CRM and ERP records in Snowflake continuously so BI reflects business systems without nightly batch ETL
  • Migrate workloads from self-managed Postgres while keeping existing syncs pointed at a compatible endpoint.
  • Mirror CRM objects into AlloyDB tables so product and internal tools query customer data with plain SQL.

Fresh analytics without loading windows

Because changes stream continuously, analysts query current data instead of waiting for last night's load.

Offload heavy reads

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

Operational data in the warehouse, minus the pipeline

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

What you can sync between Google AlloyDB 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.

Google AlloyDB objects Snowflake objects
Views Curated projections used as read-only sync sources. Schemas Namespaces within a database used to organize synced tables.
Materialized Views Precomputed aggregates refreshed and synced outward on a schedule. Tables The main landing and activation target for synced records.
Indexes Keep sync key lookups fast on high-volume tables. Views Modeled projections used as the source side of outbound syncs.
Sequences ID generation relevant when external systems insert rows. Materialized Views Precomputed results synced outward for low-latency reads.
Replication Slots Logical replication artifacts that back log-based change capture. Streams Row-level change records on a table, consumed to process deltas instead of full scans.
Databases Standard PostgreSQL databases within an AlloyDB cluster that syncs connect to. Stages File staging areas used for bulk loads into synced tables.

How the Google AlloyDB and Snowflake connectors work

Google AlloyDB

Integration surface
SQL wire protocol (PostgreSQL-compatible), with connectivity through the AlloyDB Auth Proxy or private IP
Authentication
Database credentials or IAM database authentication
Change detection
Log-based CDC via PostgreSQL logical replication; polling on timestamp columns as a fallback
Capabilities
read · write · CDC
Rate limits
No API-style rate limits; throughput is bounded by instance size

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
