Why teams connect InterSystems IRIS and Supabase

Keep InterSystems IRIS and Supabase 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 Supabase 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 Sync operational tables in IRIS bi-directionally with a CRM so business teams work on IRIS-backed data without SQL access
  • 02 Consolidate IRIS data with other databases in an analytics warehouse for cross-system reporting
  • 03 Sync application tables in Supabase with the CRM two-way so new signups appear as contacts and sales edits flow back to the app
  • 04 Mirror billing and subscription records into Supabase tables the application can join directly

Common sync patterns

Cross-engine sync

Keep the same dataset live in both InterSystems IRIS and Supabase, 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 Supabase

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 Supabase objects How this pairing syncs
Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. Tables Standard Postgres tables; the primary two-way sync target. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views SQL views expose curated slices of data for outbound replication. Views Read-side projections exposed to outbound syncs. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Schemas Schema organization scopes which tables a sync connection can see. Schemas Namespaces (public and custom) that scope sync access. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping.
Namespaces Namespaces partition databases and determine the connection context for integrations. Storage Object Metadata File metadata rows that can be joined to synced application data. Namespaces is specific to InterSystems IRIS and Storage Object Metadata to Supabase — 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. auth.users Managed authentication users, often mirrored into CRM or support systems. Stored Procedures is specific to InterSystems IRIS and auth.users to Supabase — each maps to any object or custom field on the other side.
Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. Row Level Security Policies Row-level access rules that govern what the REST layer exposes. Persistent Classes is specific to InterSystems IRIS and Row Level Security Policies to Supabase — each maps to any object or custom field on the other side.

How changes propagate between InterSystems IRIS and Supabase

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 Supabase 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 Supabase as a row-level write, with types converted between the two schemas.

Supabase InterSystems IRIS Sub-second propagation

DetectionSupabase pushes changes as they happen — webhook events backed by change data capture. Log-based CDC via Postgres logical replication, the same WAL feed that powers Supabase Realtime.

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.
  • Supabase: SQL access is bounded by connection limits (pooled connections are provided); the REST layer is subject to the platform's limits.
