Why teams connect IBM Informix and InterSystems IRIS

Keep IBM Informix and InterSystems IRIS 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 IBM Informix and InterSystems IRIS 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 Run a two-way sync between an Informix-backed retail or POS application and a CRM so store data reaches go-to-market teams.
  • 02 Keep embedded or edge Informix instances aligned with a central operational database.
  • 03 Consolidate IRIS data with other databases in an analytics warehouse for cross-system reporting
  • 04 Keep reference data consistent between an IRIS-based clinical or financial application and downstream SaaS tools

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 IBM Informix and InterSystems IRIS, so each workload runs on the engine that suits it.

What you can sync between IBM Informix and InterSystems IRIS

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.

IBM Informix objects InterSystems IRIS objects How this pairing syncs
Tables Relational tables mapped directly to sync targets. Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Read-only projections used to shape outbound data. Views SQL views expose curated slices of data for outbound replication. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Stored procedures Server-side logic sometimes invoked as part of write paths. Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Logical logs The transaction log that Informix's CDC interface reads committed changes from. Namespaces Namespaces partition databases and determine the connection context for integrations. Logical logs is specific to IBM Informix and Namespaces to InterSystems IRIS — each maps to any object or custom field on the other side.
Databases Top-level containers that scope a sync connection. Schemas Schema organization scopes which tables a sync connection can see. Databases is specific to IBM Informix and Schemas to InterSystems IRIS — each maps to any object or custom field on the other side.
Rows The unit of read and write, keyed by primary key. Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. Rows is specific to IBM Informix and Persistent Classes to InterSystems IRIS — each maps to any object or custom field on the other side.

How changes propagate between IBM Informix and InterSystems IRIS

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.

IBM Informix InterSystems IRIS 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 InterSystems IRIS as a row-level write, with types converted between the two schemas.

InterSystems IRIS IBM Informix Interval-based propagation

DetectionStacksync polls InterSystems IRIS for changes on an incremental schedule, reading only records changed since the previous pass. Polling (timestamp or query-based).

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

Rate-limit considerations

  • IBM Informix: Bounded by server resources and session limits rather than an API quota.
  • InterSystems IRIS: Constrained by database resources rather than published API rate limits.
