Why teams connect ClickHouse and Google Cloud Platform

Keep tables consistent across ClickHouse 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 ClickHouse 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

  • Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
  • Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.
  • Publish change events to Pub/Sub so downstream services react to record updates as they happen.

Shared datasets across teams

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

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.

What you can sync between ClickHouse 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.

ClickHouse objects Google Cloud Platform objects
Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Cloud Storage objects Staging area for file-based bulk loads into BigQuery and other services.
Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Pub/Sub topics Event streams used to move change events between systems in near real time.
Databases Namespaces that group tables and scope permissions for sync users. Firestore documents Document data read and written through the Firestore API for app-facing syncs.
Views Saved queries used as curated, read-only sync sources. Spanner tables Strongly consistent relational tables accessed via SQL for transactional workloads.
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. BigQuery datasets Namespaces that group tables; syncs target tables within a dataset.
Distributed tables Query-routing tables over cluster shards in self-managed deployments. BigQuery tables The primary analytics destination, written through load jobs or the Storage Write API and queried with SQL.

How the ClickHouse and Google Cloud Platform connectors work

ClickHouse

Integration surface
Native TCP protocol and HTTP interface; standard SQL dialect, with MySQL and PostgreSQL wire compatibility available
Authentication
Database credentials (username/password); ClickHouse Cloud issues per-service credentials over TLS
Change detection
No log-based CDC for consumers; incremental reads use polling on monotonic columns, and ClickHouse is usually the destination rather than the source
Capabilities
read · write

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
