Why teams connect Google Cloud Spanner and TimescaleDB

Keep Google Cloud Spanner and TimescaleDB 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 TimescaleDB 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 data from a globally distributed Spanner deployment into regional business systems.
  • Push billing or entitlement changes from finance tools into Spanner tables the application reads at runtime.
  • Replicate subscription and billing events from operational Postgres tables into Timescale hypertables for time-series analysis.
  • Keep device or asset reference tables bi-directionally in sync between TimescaleDB and an ERP.

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.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

What you can sync between Google Cloud Spanner and TimescaleDB

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 TimescaleDB objects
Interleaved tables Child rows physically co-located with parents; synced as related records. Hypertables Time-partitioned tables that hold the main time-series data; the primary read and write target in syncs.
Secondary indexes Used to make incremental read queries efficient on non-key columns. Chunks Time-bounded partitions of a hypertable; syncs read and write through the parent hypertable and never address chunks directly.
Change streams Capture inserts, updates, and deletes for log-style change data capture. Continuous Aggregates Incrementally maintained rollups that serve as pre-aggregated read sources for downstream systems.
Views Read-only projections useful for shaping data before it leaves Spanner. Regular PostgreSQL Tables Relational reference data such as devices, tenants, or accounts synced alongside the series data.
Databases Top-level containers that scope schema and sync configuration. Views Standard SQL views used to shape or filter data for consumers.
Tables Relational tables mapped one-to-one to sync targets. Schemas Postgres namespaces used to separate synced datasets by team or environment.

How the Google Cloud Spanner and TimescaleDB 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.

TimescaleDB

Integration surface
SQL wire protocol (PostgreSQL)
Authentication
Database credentials
Change detection
Log-based capture via PostgreSQL logical decoding where the deployment allows it — hypertable changes surface on the underlying chunk tables and must be remapped to the parent — or timestamp-based polling on time columns; regular Postgres tables replicate through standard logical replication
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by database resources and connection limits.
