Why teams connect Google Cloud Platform and Google Cloud Spanner

Connect Google Cloud Spanner 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 Spanner'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 Spanner 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 Spanner sync into Google Cloud Platform in real time, and result tables in Google Cloud Platform sync back into Google Cloud Spanner, 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.
  • 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.

Operational data in the warehouse, minus the pipeline

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

Serve warehouse results at database speed

Aggregates or model outputs computed in Google Cloud Platform sync into Google Cloud Spanner, where whatever reads from that database gets them without querying the warehouse.

Fresh analytics without loading windows

Because changes stream continuously, analysts query current data instead of waiting for last night's load.

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

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 Spanner objects
Cloud SQL databases Managed Postgres, MySQL, and SQL Server instances synced like ordinary relational databases. Tables Relational tables mapped one-to-one to sync targets.
Cloud Storage objects Staging area for file-based bulk loads into BigQuery and other services. Rows The unit of read and write in each sync cycle, keyed by primary key.
Pub/Sub topics Event streams used to move change events between systems in near real time. Interleaved tables Child rows physically co-located with parents; synced as related records.
Firestore documents Document data read and written through the Firestore API for app-facing syncs. Secondary indexes Used to make incremental read queries efficient on non-key columns.
Spanner tables Strongly consistent relational tables accessed via SQL for transactional workloads. Change streams Capture inserts, updates, and deletes for log-style change data capture.
BigQuery datasets Namespaces that group tables; syncs target tables within a dataset. Views Read-only projections useful for shaping data before it leaves Spanner.

How the Google Cloud Platform and Google Cloud Spanner 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 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.
