Why teams connect AWS Aurora MySQL and MariaDB

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

Teams sync AWS Aurora MySQL with MariaDB when workloads span a managed AWS database and a self-hosted or differently hosted MariaDB instance. Because both expose Databases (Schemas), Tables, and Views, the sync keeps schema and row data consistent for migrations, replicas, and cross-environment access.

Stacksync syncs tables or collections between AWS Aurora MySQL and MariaDB 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 Run a MariaDB standby of Aurora data for on-premises applications or vendor requirements.
  • 02 Migrate from MariaDB to Aurora MySQL (or back) with both schemas kept in sync during cutover.
  • 03 Keep Views and indexes consistent across two MySQL-compatible environments.
  • 04 Let operations teams edit records in a spreadsheet-style tool with changes written back to Aurora safely.

Common sync patterns

Cross-engine replica

Aurora MySQL tables and rows replicate into MariaDB tables to serve reads outside AWS.

Migration with dual-write

Databases (schemas), columns, and primary keys stay aligned while traffic moves between Aurora and MariaDB.

History-aware reporting

Aurora rows sync into MariaDB System-Versioned Tables so changes are queryable over time.

What you can sync between AWS Aurora MySQL and MariaDB

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 MariaDB objects How this pairing syncs
Databases (schemas) Logical namespaces that scope which tables a sync connection can see. Databases (Schemas) Top-level namespaces that scope a sync's reads and writes. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables The primary sync unit; each table maps one-to-one to a table or object in the paired system. Tables The primary sync target; rows map to records in connected systems. 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 Field-level mapping targets with engine-typed values. 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. Views Read-side projections used as outbound sync sources. 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. System-Versioned Tables Temporal tables that retain row history natively, useful for auditing synced changes. Foreign keys is specific to AWS Aurora MySQL and System-Versioned Tables to MariaDB — 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. JSON Columns Semi-structured payloads validated with JSON functions. Stored procedures and triggers is specific to AWS Aurora MySQL and JSON Columns to MariaDB — each maps to any object or custom field on the other side.

How changes propagate between AWS Aurora MySQL and MariaDB

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

MariaDB AWS Aurora MySQL Sub-second propagation

DetectionChanges in MariaDB are captured at the source via change data capture — no polling loop against its API. Database triggers — Stacksync creates deterministic triggers for internal logging and syncing.

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

Rate-limit considerations

  • MariaDB: No API rate limits; throughput is bounded by connection limits and server resources.
