Why teams connect AWS Aurora MySQL and AWS Aurora PostgreSQL

Keep AWS Aurora MySQL and AWS Aurora PostgreSQL synchronized in real time, across engines, regions, or services, in one or both directions.

Teams sync AWS Aurora MySQL with AWS Aurora PostgreSQL when workloads span both engines — a migration in progress, or services standardized on different databases. Tables and Rows replicate across engines with Columns and Primary keys mapped, without building custom CDC pipelines.

Stacksync syncs tables or collections between AWS Aurora MySQL and AWS Aurora PostgreSQL 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 Migrate from Aurora MySQL to Aurora PostgreSQL gradually while applications stay live.
  • 02 Serve read workloads from PostgreSQL Views and materialized views over data written in MySQL.
  • 03 Keep Primary keys and constraints consistent when the same entities exist in both engines.
  • 04 Stream row changes from Aurora into SaaS tools via binlog CDC instead of scheduled batch exports.

Common sync patterns

Cross-engine replication

Aurora MySQL Tables and Rows sync into Aurora PostgreSQL Tables continuously in both directions.

Migration without a hard cutover

Aurora MySQL Databases replicate into Aurora PostgreSQL schemas while both stay writable.

Shared reference data

selected Tables sync between engines so services on either side read the same Rows.

What you can sync between AWS Aurora MySQL and AWS Aurora PostgreSQL

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 MySQL objects AWS Aurora PostgreSQL objects How this pairing syncs
Tables The primary sync unit; each table maps one-to-one to a table or object in the paired system. Tables The core sync unit; rows are matched across systems by primary key. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Rows Inserted, updated, and deleted individually or in bulk during two-way syncs. Rows Inserted, updated, and deleted in both directions during bi-directional syncs. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Columns MySQL data types are mapped to the paired system's field types during schema setup. Columns Rich Postgres types including JSONB and arrays are mapped to the paired system's fields. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Foreign keys Express relationships that syncs preserve when mapping to related objects elsewhere. Foreign keys Relationship metadata that syncs can translate into object references elsewhere. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Can serve as read-only sync sources for derived or filtered datasets. Replication slots and publications The logical replication objects that power log-based CDC. Views is specific to AWS Aurora MySQL and Replication slots and publications to AWS Aurora PostgreSQL — each maps to any object or custom field on the other side.
Stored procedures and triggers Existing database logic keeps firing on rows written by a sync. Databases and schemas PostgreSQL's two-level namespace scopes which tables a sync connection targets. Stored procedures and triggers is specific to AWS Aurora MySQL and Databases and schemas to AWS Aurora PostgreSQL — each maps to any object or custom field on the other side.

How changes propagate between AWS Aurora MySQL and AWS Aurora PostgreSQL

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.

AWS Aurora MySQL AWS Aurora PostgreSQL Sub-second propagation

DetectionChanges in AWS Aurora MySQL are captured at the source via change data capture — no polling loop against its API. Log-based CDC via the MySQL binary log (binlog), with polling on timestamp columns as a fallback.

DeliveryEach detected change is applied to AWS Aurora PostgreSQL as a row-level write, with types converted between the two schemas.

AWS Aurora PostgreSQL AWS Aurora MySQL Sub-second propagation

DetectionChanges in AWS Aurora PostgreSQL are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication (WAL decoding through replication slots), with timestamp polling as a fallback.
