Why teams connect Firebase and InterSystems IRIS

Keep Firebase 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 Firebase 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

  • Sync Firestore user and account documents into a CRM so go-to-market teams see live product data.
  • Mirror Firestore collections into Postgres or a warehouse to run SQL analytics on app data.
  • 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

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 Firebase and InterSystems IRIS, 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 Firebase 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.

Firebase objects InterSystems IRIS objects
Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs.
Subcollections Nested collections under documents, typically flattened into related tables during sync. Views SQL views expose curated slices of data for outbound replication.
Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. Schemas Schema organization scopes which tables a sync connection can see.
Authentication Users User accounts read into CRMs and warehouses for customer records. Persistent Classes Object-model classes project to tables, so class data is reachable through SQL.
Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs.
Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. Namespaces Namespaces partition databases and determine the connection context for integrations.
