Why teams connect DuckDB and Yellowbrick

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

Common use cases

  • Sync CRM and marketing data into Yellowbrick tables so it can be joined with large fact tables for enterprise BI.
  • Land ERP transactional extracts in Yellowbrick for finance and supply-chain analytics.
  • 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.

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 Yellowbrick and keep DuckDB focused on its operational workload.

Operational data in the warehouse, minus the pipeline

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

What you can sync between DuckDB and Yellowbrick

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 Yellowbrick objects
Views SQL views used to shape or filter data for downstream consumers. Schemas Namespaces used to organize synced datasets by source or domain.
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Tables Columnar MPP tables; the primary targets for warehouse syncs.
Attached databases Additional database files or external systems attached into one session for cross-source queries. Views Logical views used to shape reads for BI and downstream syncs.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Users and Roles Access-control objects that govern what a sync service account can read and write.
Schemas Namespaces within a database used to organize tables in sync outputs. Databases Top-level containers for schemas and tables.

How the DuckDB and Yellowbrick 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

Yellowbrick

Integration surface
SQL wire protocol (PostgreSQL-compatible) with JDBC/ODBC drivers; bulk loading via the ybload utility
Authentication
Database credentials, with LDAP and Kerberos options in enterprise deployments
Change detection
Polling on timestamp columns; no exposed transaction-log CDC
Capabilities
read · write
Rate limits
No API rate limits; throughput depends on cluster sizing, and bulk loads should use ybload rather than row-by-row inserts.
