Why teams connect InterSystems IRIS and OpenSearch

Keep InterSystems IRIS and OpenSearch 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 InterSystems IRIS and OpenSearch 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 operational tables in IRIS bi-directionally with a CRM so business teams work on IRIS-backed data without SQL access
  • Consolidate IRIS data with other databases in an analytics warehouse for cross-system reporting
  • Stream CRM records such as accounts, contacts, and tickets into OpenSearch to power internal search across customer data.
  • Sync product catalogs from an ERP or database into the indexes that back storefront search.

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 InterSystems IRIS and OpenSearch, 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 InterSystems IRIS and OpenSearch

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.

InterSystems IRIS objects OpenSearch objects
Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. Index templates Mapping and settings presets applied to new indexes a sync creates
Views SQL views expose curated slices of data for outbound replication. Ingest pipelines Server-side processors that transform documents as they are written
Schemas Schema organization scopes which tables a sync connection can see. Data streams Append-oriented time-series storage for logs and events pushed from source systems
Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. Snapshots Backup artifacts, relevant when reseeding an index from a repository
Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. Indexes The core container; synced records land in indexes with defined mappings
Namespaces Namespaces partition databases and determine the connection context for integrations. Documents JSON records written via the index and bulk APIs and read via search queries
