Why teams connect AWS Aurora PostgreSQL and Firebase

Keep AWS Aurora PostgreSQL and Firebase 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 AWS Aurora PostgreSQL and Firebase 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

  • Expose ERP records such as customers, orders, and invoices as Postgres tables the engineering team can query and update with plain SQL.
  • Capture row-level changes with logical replication and propagate them to SaaS tools without batch jobs.
  • Write CRM-side changes (plan, status, owner) back into Firestore documents the app reads.
  • Combine Firebase Authentication users with billing and CRM records into one customer table.

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 AWS Aurora PostgreSQL and Firebase

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.

AWS Aurora PostgreSQL objects Firebase objects
Primary keys and constraints Identify rows for upserts and enforce integrity on sync writes. Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward.
Views and materialized views Usable as read-only sources for filtered or precomputed sync datasets. Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects.
Foreign keys Relationship metadata that syncs can translate into object references elsewhere. Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems.
Replication slots and publications The logical replication objects that power log-based CDC. Subcollections Nested collections under documents, typically flattened into related tables during sync.
Databases and schemas PostgreSQL's two-level namespace scopes which tables a sync connection targets. Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path.
Tables The core sync unit; rows are matched across systems by primary key. Authentication Users User accounts read into CRMs and warehouses for customer records.
