Why teams connect DuckDB and TimescaleDB

Keep DuckDB and TimescaleDB synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between DuckDB and TimescaleDB continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • 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.
  • Consolidate metrics from several services into one hypertable to serve a single reporting layer.
  • Sync product or IoT telemetry stored in TimescaleDB into a CRM so account teams see usage metrics next to the customer record.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

Cross-engine sync

Keep the same dataset live in both DuckDB and TimescaleDB, so each workload runs on the engine that suits it.

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

What you can sync between DuckDB and TimescaleDB

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 TimescaleDB objects
Attached databases Additional database files or external systems attached into one session for cross-source queries. Continuous Aggregates Incrementally maintained rollups that serve as pre-aggregated read sources for downstream systems.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Regular PostgreSQL Tables Relational reference data such as devices, tenants, or accounts synced alongside the series data.
Schemas Namespaces within a database used to organize tables in sync outputs. Views Standard SQL views used to shape or filter data for consumers.
Tables Columnar tables created via SQL; the destination for materialized sync data. Schemas Postgres namespaces used to separate synced datasets by team or environment.
Views SQL views used to shape or filter data for downstream consumers. Hypertables Time-partitioned tables that hold the main time-series data; the primary read and write target in syncs.
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Chunks Time-bounded partitions of a hypertable; syncs read and write through the parent hypertable and never address chunks directly.
What ships with DuckDB ⇄ TimescaleDB

At scale

Event queues

Handle millions of events per minute without losing a single DuckDB or TimescaleDB record.

Observability

Monitoring

Track your DuckDB ⇄ TimescaleDB sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between DuckDB and TimescaleDB.

How the DuckDB and TimescaleDB 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

TimescaleDB

Integration surface
SQL wire protocol (PostgreSQL)
Authentication
Database credentials
Change detection
Log-based capture via PostgreSQL logical decoding where the deployment allows it — hypertable changes surface on the underlying chunk tables and must be remapped to the parent — or timestamp-based polling on time columns; regular Postgres tables replicate through standard logical replication
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by database resources and connection limits.
