Why teams connect Amazon Aurora and Google Cloud SQL

Keep Amazon Aurora and Google Cloud SQL 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 Amazon Aurora and Google Cloud SQL 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

  • Consolidate several Aurora clusters into one reporting database.
  • Write enriched or scored records from analytics pipelines back into the Aurora tables that power an application.
  • Migrate from a self-managed database by syncing Cloud SQL and the legacy system during cutover.
  • Keep an internal admin application backed by Cloud SQL consistent with an ERP or billing system.

Cross-engine sync

Keep the same dataset live in both Amazon Aurora and Google Cloud SQL, 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.

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

What you can sync between Amazon Aurora 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.

Amazon Aurora objects Google Cloud SQL objects
Tables Relational tables synced bi-directionally at row level. Tables Mapped directly to sync targets; schema changes can be propagated.
Views Read-only query-backed sources for downstream syncs. Rows Read and written by primary key during each sync cycle.
Materialized Views Precomputed result sets (PostgreSQL-compatible clusters) readable as sources. Views Read-only sources for shaping data before syncing it out.
Columns and Data Types Standard MySQL or PostgreSQL types mapped during field mapping. Transaction logs MySQL binlog or PostgreSQL WAL, the source for log-based change capture.
Primary and Foreign Keys Constraints used to identify records and preserve relational integrity in syncs. Instances The managed MySQL, PostgreSQL, or SQL Server server a sync connects to.
Read Replicas Reader endpoints that syncs can target to keep load off the writer. Databases Scope the tables included in a sync configuration.

How the Amazon Aurora and Google Cloud SQL connectors work

Amazon Aurora

Integration surface
MySQL or PostgreSQL wire protocol (SQL); optional RDS Data API over HTTPS
Authentication
Database credentials or IAM database authentication
Change detection
Log-based CDC: binlog on MySQL-compatible clusters, logical replication/decoding on PostgreSQL-compatible clusters; polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits for wire-protocol access; throughput is bounded by instance class and connection 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 Amazon Aurora 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.
