Why teams connect Citus and Starburst Enterprise

Connect Citus and Starburst Enterprise 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 Starburst Enterprise, 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 Starburst Enterprise in real time, and result tables in Starburst Enterprise sync back into Citus, with schema and type mapping between the two systems handled for you.

Common use cases

  • Expose Iceberg or Hive lake tables to sync jobs through one SQL endpoint without moving the data first
  • Consolidate reads from multiple databases behind a single connection instead of maintaining one integration per source
  • Sync high-volume event or tenant data from a Citus cluster into a warehouse for cross-tenant analytics.
  • Write CRM or billing records into reference tables so distributed queries can join operational context locally on every node.

Offload heavy reads

Point analytical queries at the synced copy in Starburst Enterprise and keep Citus focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from Citus land in Starburst Enterprise as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in Starburst Enterprise sync into Citus, where whatever reads from that database gets them without querying the warehouse.

What you can sync between Citus and Starburst Enterprise

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 Starburst Enterprise objects
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Schemas Namespaces within a catalog, mirroring the underlying source's databases or schemas.
Views Curated projections over distributed data, often used as read-only sync sources. Tables Queryable relations; writes pass through to sources whose connectors support them.
Sequences Key generators that matter when external writes must not collide with application inserts. Views Engine-level SQL views used to shape federated data before syncing it out.
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Materialized views Precomputed results that make repeated sync reads cheaper.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Columns Typed per the Trino type system, mapped from each source's native types.
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Catalogs Each catalog maps to a connector (Iceberg, Hive, PostgreSQL, and others) exposing an external source.

How the Citus and Starburst Enterprise 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

Starburst Enterprise

Integration surface
ANSI SQL over JDBC/ODBC drivers and the Trino client REST protocol
Authentication
Deployment-dependent: username/password, LDAP, OAuth 2.0, or Kerberos
Change detection
Query-based polling; Starburst is a query engine and exposes no change log of its own
Capabilities
read · write
Rate limits
Throughput is governed by cluster sizing and resource groups rather than API quotas
