Why teams connect DuckDB and IBM Informix

Keep DuckDB and IBM Informix 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 IBM Informix 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

  • 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.
  • Run a two-way sync between an Informix-backed retail or POS application and a CRM so store data reaches go-to-market teams.
  • Keep embedded or edge Informix instances aligned with a central operational database.

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.

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

Regional or environment copies

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

What you can sync between DuckDB and IBM Informix

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 IBM Informix objects
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Rows The unit of read and write, keyed by primary key.
Attached databases Additional database files or external systems attached into one session for cross-source queries. Views Read-only projections used to shape outbound data.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. TimeSeries objects Informix's native time-series type, usually exposed to syncs through virtual tables.
Schemas Namespaces within a database used to organize tables in sync outputs. Stored procedures Server-side logic sometimes invoked as part of write paths.
Tables Columnar tables created via SQL; the destination for materialized sync data. Logical logs The transaction log that Informix's CDC interface reads committed changes from.
Views SQL views used to shape or filter data for downstream consumers. Databases Top-level containers that scope a sync connection.

How the DuckDB and IBM Informix 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

IBM Informix

Integration surface
SQL over JDBC/ODBC drivers; DRDA connectivity is also supported
Authentication
Database credentials
Change detection
Informix's Change Data Capture API reading committed changes from logical logs; polling as a fallback
Capabilities
read · write · CDC
Rate limits
Bounded by server resources and session limits rather than an API quota.
