Why teams connect CockroachDB and Google Cloud SQL

Keep CockroachDB 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 CockroachDB 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

  • Use changefeeds to propagate row changes from a multi-region cluster into a warehouse or search index.
  • Keep reference data consistent between CockroachDB and regional application databases.
  • 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.

Cross-engine sync

Keep the same dataset live in both CockroachDB 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 CockroachDB 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.

CockroachDB objects Google Cloud SQL objects
Sequences ID generators that matter when writes originate from an external system. Transaction logs MySQL binlog or PostgreSQL WAL, the source for log-based change capture.
Changefeeds Built-in CDC streams that emit row-level changes to external sinks. Instances The managed MySQL, PostgreSQL, or SQL Server server a sync connects to.
Databases Logical containers a sync connects to, addressed like PostgreSQL databases. Databases Scope the tables included in a sync configuration.
Schemas Namespaces within a database used to isolate synced tables from application tables. Schemas Namespace tables in PostgreSQL and SQL Server instances.
Tables The core read/write target; rows sync bi-directionally with SaaS objects or other databases. Tables Mapped directly to sync targets; schema changes can be propagated.
Views Read-only projections used as curated sync sources. Rows Read and written by primary key during each sync cycle.

How the CockroachDB and Google Cloud SQL connectors work

CockroachDB

Integration surface
SQL wire protocol (PostgreSQL-compatible)
Authentication
Database credentials with TLS; client certificates or SCRAM password auth
Change detection
CDC via changefeeds, which stream row-level changes; polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits in the SaaS sense; throughput is bounded by cluster capacity

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.
