Why teams connect AWS Aurora PostgreSQL and Google AlloyDB

Keep AWS Aurora PostgreSQL and Google AlloyDB 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 Google AlloyDB 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

  • Keep a customer-facing Aurora database aligned with an internal admin tool, with writes accepted on both sides.
  • Feed operational dashboards from a read replica while the writer handles sync traffic.
  • Use logical replication to feed AlloyDB changes into warehouses or event pipelines without batch jobs.
  • Consolidate SaaS data into AlloyDB and serve analytics from its columnar engine without a separate OLAP store.

Cross-engine sync

Keep the same dataset live in both AWS Aurora PostgreSQL and Google AlloyDB, 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 AWS Aurora PostgreSQL and Google AlloyDB

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 Google AlloyDB objects
Rows Inserted, updated, and deleted in both directions during bi-directional syncs. Schemas Namespaces used to separate synced SaaS data from application tables.
Columns Rich Postgres types including JSONB and arrays are mapped to the paired system's fields. Tables Primary read/write target for bi-directional sync with CRMs and other systems.
Primary keys and constraints Identify rows for upserts and enforce integrity on sync writes. Views Curated projections used as read-only sync sources.
Views and materialized views Usable as read-only sources for filtered or precomputed sync datasets. Materialized Views Precomputed aggregates refreshed and synced outward on a schedule.
Foreign keys Relationship metadata that syncs can translate into object references elsewhere. Indexes Keep sync key lookups fast on high-volume tables.
Replication slots and publications The logical replication objects that power log-based CDC. Sequences ID generation relevant when external systems insert rows.
