Why teams connect Google Cloud Platform and Google Cloud SQL

Connect Google Cloud SQL and Google Cloud Platform 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 Cloud SQL's rows in Google Cloud Platform, 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 Cloud SQL 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 Cloud SQL sync into Google Cloud Platform in real time, and result tables in Google Cloud Platform sync back into Google Cloud SQL, with schema and type mapping between the two systems handled for you.

Common use cases

  • Publish change events to Pub/Sub so downstream services react to record updates as they happen.
  • Keep an internal admin application backed by Cloud SQL consistent with an ERP or billing system.
  • Migrate from a self-managed database by syncing Cloud SQL and the legacy system during cutover.

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 Google Cloud Platform and keep Google Cloud SQL focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from Google Cloud SQL land in Google Cloud Platform as they change, replacing hand-built CDC and batch extract jobs.

What you can sync between Google Cloud Platform and Google Cloud SQL

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 Cloud Platform objects Google Cloud SQL objects
Pub/Sub topics Event streams used to move change events between systems in near real time. Views Read-only sources for shaping data before syncing it out.
Firestore documents Document data read and written through the Firestore API for app-facing syncs. Transaction logs MySQL binlog or PostgreSQL WAL, the source for log-based change capture.
Spanner tables Strongly consistent relational tables accessed via SQL for transactional workloads. Instances The managed MySQL, PostgreSQL, or SQL Server server a sync connects to.
BigQuery datasets Namespaces that group tables; syncs target tables within a dataset. Databases Scope the tables included in a sync configuration.
BigQuery tables The primary analytics destination, written through load jobs or the Storage Write API and queried with SQL. Schemas Namespace tables in PostgreSQL and SQL Server instances.
Cloud SQL databases Managed Postgres, MySQL, and SQL Server instances synced like ordinary relational databases. Tables Mapped directly to sync targets; schema changes can be propagated.
What ships with Google Cloud Platform ⇄ Google Cloud SQL

Connect Google Cloud Platform and Google Cloud SQL for flexible, real-time data sync.

No-code + pro-code

Workflow automation

Trigger automated workflows whenever Google Cloud Platform or Google Cloud SQL data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single Google Cloud Platform or Google Cloud SQL record.

Observability

Monitoring

Track your Google Cloud Platform ⇄ Google Cloud SQL sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between Google Cloud Platform and Google Cloud SQL.

How the Google Cloud Platform and Google Cloud SQL connectors work

Google Cloud Platform

Integration surface
Per-service REST and gRPC APIs; BigQuery speaks SQL and Cloud SQL exposes standard database wire protocols
Authentication
IAM service accounts with OAuth 2.0 tokens
Change detection
Varies by service: log-based CDC on Cloud SQL (logical replication or binlog, also via Datastream), Pub/Sub for event delivery, polling for BigQuery tables
Capabilities
read · write · CDC · webhooks
Rate limits
Quotas are set per service and per project; BigQuery, Pub/Sub, and Cloud SQL each enforce their own limits

Google Cloud SQL

Integration surface
Native SQL wire protocols (MySQL, PostgreSQL, SQL Server) plus a REST admin API for instance management
Authentication
Database credentials; IAM database authentication is available for MySQL and PostgreSQL
Change detection
Engine-dependent log-based CDC: MySQL binlog, PostgreSQL logical replication, SQL Server change tracking; polling as a fallback
Capabilities
read · write · CDC
Rate limits
Constrained by instance size and connection limits rather than API quotas.
How it works

How to connect Google Cloud Platform to Google Cloud SQL — three steps, no code

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

  1. 01

    Connect your apps

    Authenticate Google Cloud Platform and Google Cloud SQL with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
