Why teams connect BigQuery and CockroachDB

Connect CockroachDB and BigQuery 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 CockroachDB's rows in BigQuery, 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 CockroachDB where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in CockroachDB sync into BigQuery in real time, and result tables in BigQuery sync back into CockroachDB, with schema and type mapping between the two systems handled for you.

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
  • Consolidate data from several SaaS tools into one distributed SQL store that survives zone failures.
  • Write application events from CockroachDB back to CRM fields to give go-to-market teams product context.

Fresh analytics without loading windows

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

Offload heavy reads

Point analytical queries at the synced copy in BigQuery and keep CockroachDB focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from CockroachDB land in BigQuery as they change, replacing hand-built CDC and batch extract jobs.

What you can sync between BigQuery and CockroachDB

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 CockroachDB objects
Datasets Organizational container — you pick which dataset’s tables to sync. Views Read-only projections used as curated sync sources.
Projects Connection scope: the service account grants access per project. Indexes Secondary indexes that keep sync lookup queries fast on key columns.
Tables The syncable unit: only tables can be synced per the Stacksync docs. Sequences ID generators that matter when writes originate from an external system.
Partitioned tables Synced like regular tables; partition columns map to target fields. Changefeeds Built-in CDC streams that emit row-level changes to external sinks.
Clustered tables Supported; clustering is transparent to the sync. Databases Logical containers a sync connects to, addressed like PostgreSQL databases.

How the BigQuery and CockroachDB 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

CockroachDB

Integration surface
SQL wire protocol (PostgreSQL-compatible)
Authentication
Database credentials with TLS; client certificates or SCRAM password auth
Change detection
CDC via changefeeds, which stream row-level changes; polling as a fallback
Capabilities

Rate limits
No API rate limits in the SaaS sense; throughput is bounded by cluster capacity
