Why teams connect InterSystems IRIS and MariaDB

Keep InterSystems IRIS and MariaDB 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 MariaDB 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

  • Replicate IRIS tables to Postgres so application teams can build against a familiar database
  • Sync operational tables in IRIS bi-directionally with a CRM so business teams work on IRIS-backed data without SQL access
  • Two-way sync between a MariaDB application database and a CRM so both systems hold the same customer records
  • Replicate ERP or billing master data into MariaDB databases that power customer-facing applications

Cross-engine sync

Keep the same dataset live in both InterSystems IRIS and MariaDB, 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.

Shared reference data between services

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

What you can sync between InterSystems IRIS and MariaDB

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 MariaDB objects
Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. Databases (Schemas) Top-level namespaces that scope a sync's reads and writes.
Namespaces Namespaces partition databases and determine the connection context for integrations. Tables The primary sync target; rows map to records in connected systems.
Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. Views Read-side projections used as outbound sync sources.
Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. Columns Field-level mapping targets with engine-typed values.
Views SQL views expose curated slices of data for outbound replication. Primary and Unique Keys Match keys for idempotent upserts.
Schemas Schema organization scopes which tables a sync connection can see. System-Versioned Tables Temporal tables that retain row history natively, useful for auditing synced changes.
