Why teams connect DuckDB and Starburst Enterprise

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

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

Common use cases

  • Write curated or reconciled results back to lakehouse tables through connectors that support inserts
  • Read federated views that join warehouse, lake, and database tables, then sync the result into operational tools like a CRM
  • Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.
  • Push aggregates computed in DuckDB out to a CRM or business tools so analysis results reach operational systems.

Serve warehouse results at database speed

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

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 Starburst Enterprise and keep DuckDB focused on its operational workload.

What you can sync between DuckDB 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.

DuckDB objects Starburst Enterprise objects
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Columns Typed per the Trino type system, mapped from each source's native types.
Attached databases Additional database files or external systems attached into one session for cross-source queries. Catalogs Each catalog maps to a connector (Iceberg, Hive, PostgreSQL, and others) exposing an external source.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Schemas Namespaces within a catalog, mirroring the underlying source's databases or schemas.
Schemas Namespaces within a database used to organize tables in sync outputs. Tables Queryable relations; writes pass through to sources whose connectors support them.
Tables Columnar tables created via SQL; the destination for materialized sync data. Views Engine-level SQL views used to shape federated data before syncing it out.
Views SQL views used to shape or filter data for downstream consumers. Materialized views Precomputed results that make repeated sync reads cheaper.

How the DuckDB and Starburst Enterprise connectors work

DuckDB

Integration surface
In-process SQL engine via client libraries (Python, Node.js, JDBC, CLI); no server or network API by default
Authentication
None built in; access control is file-system level (MotherDuck adds token auth for its hosted service)
Change detection
Polling or full re-reads; no change feed or transaction log API
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by local compute and I/O

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
