Why teams connect Google Cloud Platform and MotherDuck

Keep tables consistent across Google Cloud Platform and MotherDuck, 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 Google Cloud Platform and MotherDuck 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

  • Publish change events to Pub/Sub so downstream services react to record updates as they happen.
  • Sync modeled MotherDuck tables outward to operational tools for activation
  • Share curated, synced datasets with other teams through read-only database shares

Consolidation after M&A

Bring the acquired company's warehouse data across continuously instead of through one-off dumps.

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.

What you can sync between Google Cloud Platform and MotherDuck

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 MotherDuck objects
Cloud Storage objects Staging area for file-based bulk loads into BigQuery and other services. Tables The main landing target for synced records and source for analysis.
Pub/Sub topics Event streams used to move change events between systems in near real time. Views Modeled projections used as outbound sync sources.
Firestore documents Document data read and written through the Firestore API for app-facing syncs. Database Shares Read-only copies of a database shared with other users or teams.
Spanner tables Strongly consistent relational tables accessed via SQL for transactional workloads. Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries.
BigQuery datasets Namespaces that group tables; syncs target tables within a dataset. Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes.
BigQuery tables The primary analytics destination, written through load jobs or the Storage Write API and queried with SQL. Schemas Namespaces within a database used to organize synced tables.

How the Google Cloud Platform and MotherDuck 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

MotherDuck

Integration surface
SQL through DuckDB clients and drivers using a MotherDuck (md:) connection
Authentication
Access token created in MotherDuck (Settings > General > Create Token), pasted into Stacksync; database name and schema configurable if not using defaults
Change detection
Polling; no log-based CDC or webhook surface is exposed
Capabilities
read · write
Rate limits
Subject to the platform's compute and concurrency limits rather than per-request API rate limits
