Why teams connect BigQuery and Google Cloud Platform

Keep tables consistent across BigQuery and Google Cloud Platform, for a migration, a multi-warehouse stack, or a dataset two platforms both need.

Companies end up with two warehouses for practical reasons: a migration in progress, teams that standardized on different platforms, an acquisition, or tools that only connect to one of them. The result is the same dataset maintained twice, with duplicated pipelines and numbers that almost match.

Stacksync syncs tables between BigQuery and Google Cloud Platform continuously, in either or both directions. Rows changed on one platform appear on the other within seconds, with schema and type mapping handled, so both warehouses answer questions with the same data.

Common use cases

  • Maintain a customer master table in BigQuery joined across CRM, billing, and support sources
  • Feed ML feature tables in BigQuery from operational systems on a continuous schedule
  • Publish change events to Pub/Sub so downstream services react to record updates as they happen.
  • Sync operational CRM and ERP data into BigQuery for analytics without building custom pipelines.

Migration without a big bang

When one platform is replacing the other, keep tables mirrored while workloads move over gradually, and cut over with nothing to backfill.

Serve tools that only connect to one platform

Mirror the datasets a BI tool, notebook, or application needs onto the platform it can actually reach.

Shared datasets across teams

Where different teams run different warehouses, sync the curated tables both rely on so their metrics agree by construction.

What you can sync between BigQuery and Google Cloud Platform

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.

BigQuery objects Google Cloud Platform objects
Datasets Organizational container — you pick which dataset’s tables to sync. Firestore documents Document data read and written through the Firestore API for app-facing syncs.
Projects Connection scope: the service account grants access per project. Spanner tables Strongly consistent relational tables accessed via SQL for transactional workloads.
Tables The syncable unit: only tables can be synced per the Stacksync docs. BigQuery datasets Namespaces that group tables; syncs target tables within a dataset.
Partitioned tables Synced like regular tables; partition columns map to target fields. BigQuery tables The primary analytics destination, written through load jobs or the Storage Write API and queried with SQL.
Clustered tables Supported; clustering is transparent to the sync. Cloud SQL databases Managed Postgres, MySQL, and SQL Server instances synced like ordinary relational databases.

How the BigQuery and Google Cloud Platform connectors work

BigQuery

Integration surface
GoogleSQL via the BigQuery REST API, client libraries, JDBC/ODBC drivers, and the Storage Read/Write APIs
Authentication
Google Cloud service account: create a dedicated service account, grant roles (BigQuery Data Editor, BigQuery Job User, Cloud Functions Service Agent, Cloud Run Developer, Eventarc Event Receiver
Change detection
Real-time notification service deployed into your Google Cloud project: Eventarc ("a notification service that enables real-time updates to happen") with a Cloud Run "secure portal for real-time notification service in
Capabilities
read · write · CDC
Rate limits
Subject to Google Cloud quotas on queries, DML, and streaming; DML is supported but the platform favors append-heavy batch and streaming loads over row-at-a-time writes
BigQuery setup guide

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

Rate limits
Quotas are set per service and per project; BigQuery, Pub/Sub, and Cloud SQL each enforce their own limits
How it works

How to connect BigQuery to Google Cloud Platform — three steps, no code
