Why teams connect Citus and Google Cloud Platform

Connect Citus 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 Citus'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 Citus where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in Citus sync into Google Cloud Platform in real time, and result tables in Google Cloud Platform sync back into Citus, 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 per-tenant rows from distributed tables into per-customer reporting databases.
  • Sync high-volume event or tenant data from a Citus cluster into a warehouse for cross-tenant analytics.

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 Google Cloud Platform and keep Citus focused on its operational workload.

Operational data in the warehouse, minus the pipeline

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

What you can sync between Citus 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.

Citus objects Google Cloud Platform objects
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. BigQuery tables The primary analytics destination, written through load jobs or the Storage Write API and queried with SQL.
Views Curated projections over distributed data, often used as read-only sync sources. Cloud SQL databases Managed Postgres, MySQL, and SQL Server instances synced like ordinary relational databases.
Sequences Key generators that matter when external writes must not collide with application inserts. Cloud Storage objects Staging area for file-based bulk loads into BigQuery and other services.
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Pub/Sub topics Event streams used to move change events between systems in near real time.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Firestore documents Document data read and written through the Firestore API for app-facing syncs.
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Spanner tables Strongly consistent relational tables accessed via SQL for transactional workloads.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between Citus and Google Cloud Platform.

How the Citus and Google Cloud Platform connectors work

Citus

Integration surface
PostgreSQL wire protocol; any standard Postgres driver connects to the coordinator node
Authentication
Database credentials (standard PostgreSQL authentication; managed deployments add cloud IAM options)
Change detection
PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres
Capabilities
read · write · CDC

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
How it works
