Why teams connect Citus and IBM Informix

Keep Citus 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 Citus 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

  • 01 Write CRM or billing records into reference tables so distributed queries can join operational context locally on every node.
  • 02 Use a Citus cluster as the scalable operational store behind a customer-facing app while syncing summaries back to internal tools.
  • 03 Feed inventory and transaction data from legacy Informix applications into modern ERPs during migration.
  • 04 Replicate Informix tables into a cloud warehouse using its change data capture interface for near-real-time reporting.

Common sync patterns

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.

Cross-engine sync

Keep the same dataset live in both Citus and IBM Informix, so each workload runs on the engine that suits it.

What you can sync between Citus 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.

Citus objects IBM Informix objects How this pairing syncs
Views Curated projections over distributed data, often used as read-only sync sources. Views Read-only projections used to shape outbound data. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Sequences Key generators that matter when external writes must not collide with application inserts. TimeSeries objects Informix's native time-series type, usually exposed to syncs through virtual tables. Sequences is specific to Citus and TimeSeries objects to IBM Informix — each maps to any object or custom field on the other side.
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Stored procedures Server-side logic sometimes invoked as part of write paths. Distributed tables is specific to Citus and Stored procedures to IBM Informix — each maps to any object or custom field on the other side.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Logical logs The transaction log that Informix's CDC interface reads committed changes from. Reference tables is specific to Citus and Logical logs to IBM Informix — each maps to any object or custom field on the other side.
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Databases Top-level containers that scope a sync connection. Local tables is specific to Citus and Databases to IBM Informix — each maps to any object or custom field on the other side.
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Tables Relational tables mapped directly to sync targets. Schemas is specific to Citus and Tables to IBM Informix — each maps to any object or custom field on the other side.

How changes propagate between Citus and IBM Informix

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Citus IBM Informix Sub-second propagation

DetectionChanges in Citus are captured at the source via change data capture — no polling loop against its API. PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres.

DeliveryEach detected change is applied to IBM Informix as a row-level write, with types converted between the two schemas.

IBM Informix Citus Sub-second propagation

DetectionChanges in IBM Informix are captured at the source via change data capture — no polling loop against its API. Informix's Change Data Capture API reading committed changes from logical logs.

DeliveryEach detected change is applied to Citus as a row-level write, with types converted between the two schemas.
