Why teams connect Google Cloud Spanner and YugabyteDB

Keep Google Cloud Spanner and YugabyteDB 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 Google Cloud Spanner and YugabyteDB 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

  • Push billing or entitlement changes from finance tools into Spanner tables the application reads at runtime.
  • Use change streams to feed near-real-time copies of operational tables into an analytics warehouse.
  • Two-way sync between YugabyteDB application tables and a CRM so product data and account records stay consistent.
  • Sync reference data such as pricing or entitlements from an ERP into YugabyteDB for globally distributed low-latency reads.

Cross-engine sync

Keep the same dataset live in both Google Cloud Spanner and YugabyteDB, 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 Google Cloud Spanner and YugabyteDB

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 Spanner objects YugabyteDB objects
Interleaved tables Child rows physically co-located with parents; synced as related records. Sequences ID generation objects relevant when syncing writes into YSQL tables.
Secondary indexes Used to make incremental read queries efficient on non-key columns. CDC Streams Change streams over the storage-layer WAL consumed through logical replication or Debezium-compatible connectors.
Change streams Capture inserts, updates, and deletes for log-style change data capture. Databases and Keyspaces Top-level containers for the YSQL (Postgres-style) and YCQL (Cassandra-style) APIs respectively.
Views Read-only projections useful for shaping data before it leaves Spanner. Tables Distributed SQL tables split into tablets; the primary read and write targets.
Databases Top-level containers that scope schema and sync configuration. Indexes Global secondary indexes maintained transactionally alongside table writes.
Tables Relational tables mapped one-to-one to sync targets. Materialized Views Precomputed query results available in YSQL for read-side shaping.

How the Google Cloud Spanner and YugabyteDB connectors work

Google Cloud Spanner

Integration surface
gRPC/REST client API with SQL query surface (GoogleSQL and PostgreSQL-interface dialects)
Authentication
Google Cloud IAM (service accounts)
Change detection
Change streams (log-style CDC), or timestamp-based polling queries
Capabilities
read · write · CDC
Rate limits
Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.

YugabyteDB

Integration surface
SQL wire protocol (PostgreSQL-compatible YSQL) plus a Cassandra-compatible YCQL API
Authentication
Database credentials
Change detection
Native CDC from the write-ahead log via PostgreSQL logical replication or Debezium-compatible connectors
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput scales with cluster nodes and tablet distribution.
