Why teams connect InterSystems IRIS and SAP Hana

Keep InterSystems IRIS and SAP Hana 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 SAP Hana 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 enriched or corrected records from SaaS apps back into IRIS tables for on-platform processing
  • 02 Replicate IRIS tables to Postgres so application teams can build against a familiar database
  • 03 Detect inserts, updates, and deletes on high-write tables via AFTER triggers or a last-modified column and replicate the deltas downstream near-real-time.
  • 04 Read SYS.TABLES and TABLE_COLUMNS system views to auto-discover schema and generate field mappings when new tables are added to the sync.

Common sync patterns

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 InterSystems IRIS and SAP Hana

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 SAP Hana objects How this pairing syncs
Schemas Schema organization scopes which tables a sync connection can see. Schemas Namespaces that group tables and views; the connector targets a schema and enumerates its objects from the catalog to build the sync. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. System-versioned temporal tables Column store tables with a history table tracking each row's validity period; used to reconstruct update and delete history for change capture. Persistent Classes is specific to InterSystems IRIS and System-versioned temporal tables to SAP Hana — each maps to any object or custom field on the other side.
Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. System views (SYS schema) Catalog and monitoring views such as SYS.TABLES and TABLE_COLUMNS; read to discover schema and auto-generate field mappings for new tables. Globals is specific to InterSystems IRIS and System views (SYS schema) to SAP Hana — each maps to any object or custom field on the other side.
Namespaces Namespaces partition databases and determine the connection context for integrations. Column store tables HANA's default table type, optimized for analytics; synced two-way as rows over the SQL interface with the primary key driving upserts and delete tracking. Namespaces is specific to InterSystems IRIS and Column store tables to SAP Hana — each maps to any object or custom field on the other side.
Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. Row store tables OLTP-oriented tables held fully in memory; read and written the same way through the SAP HANA client for high-write operational tables. Stored Procedures is specific to InterSystems IRIS and Row store tables to SAP Hana — each maps to any object or custom field on the other side.
Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. Calculation views Modeled analytic views over base tables; read-only sources for pushing aggregated or joined results into a warehouse or downstream app. Tables is specific to InterSystems IRIS and Calculation views to SAP Hana — each maps to any object or custom field on the other side.

How changes propagate between InterSystems IRIS and SAP Hana

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.

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

SAP Hana InterSystems IRIS Sub-second propagation

DetectionChanges in SAP Hana are captured at the source via change data capture — no polling loop against its API. Polling on a last-modified timestamp column, or AFTER INSERT/UPDATE/DELETE triggers writing to a shadow table.

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

Rate-limit considerations

  • InterSystems IRIS: Constrained by database resources rather than published API rate limits.
  • SAP Hana: No SaaS-style request quota; throughput is bounded by connection limits, statement memory caps, and workload-class admission control (concurrency/memory limits) that share capacity with production queries.
