Why teams connect DuckDB and Teradata Vantage

Connect DuckDB and Teradata Vantage 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 Teradata Vantage, 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 Teradata Vantage in real time, and result tables in Teradata Vantage sync back into DuckDB, with schema and type mapping between the two systems handled for you.

Common use cases

  • Sync curated Vantage tables into a CRM so frontline teams act on warehouse-computed customer attributes
  • Land SaaS and ERP data into Vantage to join with existing enterprise history
  • Use DuckDB as a transform step: read synced Parquet exports, aggregate with SQL, and write results back to an operational database.
  • Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.

Offload heavy reads

Point analytical queries at the synced copy in Teradata Vantage and keep DuckDB focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from DuckDB land in Teradata Vantage as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

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

What you can sync between DuckDB and Teradata Vantage

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 Teradata Vantage objects
Views SQL views used to shape or filter data for downstream consumers. Views The conventional access layer in Teradata shops; syncs often read views rather than base tables.
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Macros Stored parameterized SQL that encapsulates repeatable reads.
Attached databases Additional database files or external systems attached into one session for cross-source queries. Stored procedures Server-side logic sometimes invoked as part of load workflows.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Users In Teradata, users are databases with a password, and they own objects and space.
Schemas Namespaces within a database used to organize tables in sync outputs. Columns Teradata SQL types mapped to the paired system's field types during sync.
Tables Columnar tables created via SQL; the destination for materialized sync data. Databases Hierarchical containers that own tables and space allocations.

How the DuckDB and Teradata Vantage 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

Teradata Vantage

Integration surface
ANSI SQL over JDBC/ODBC/.NET drivers; REST access available through Teradata's query service
Authentication
Database credentials; LDAP or Kerberos in enterprise deployments
Change detection
Query-based polling; the SQL surface exposes no externally consumable change log
Capabilities
read · write
Rate limits
Concurrency is governed by workload management rules on the system rather than API quotas
