Why teams connect Amazon Aurora and Azure SQL Database

Keep Amazon Aurora and Azure SQL Database 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 Amazon Aurora and Azure SQL Database 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 Write enriched or scored records from analytics pipelines back into the Aurora tables that power an application.
  • 02 Offload sync reads to Aurora reader endpoints to avoid load on the writer instance.
  • 03 Expose SaaS data (billing, support tickets) as tables in Azure SQL for reporting teams already on Microsoft tooling.
  • 04 Replicate Azure SQL tables to a warehouse without building custom CDC pipelines.

Common sync patterns

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 Amazon Aurora and Azure SQL Database, 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 Amazon Aurora and Azure SQL Database

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.

Amazon Aurora objects Azure SQL Database objects How this pairing syncs
Schemas Namespaces (PostgreSQL) or database-level grouping (MySQL) used in table selection. Schemas Namespaces that organize tables and control which objects a sync user can reach. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables Relational tables synced bi-directionally at row level. Tables The primary sync target; rows map one-to-one to records in the paired system. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Read-only query-backed sources for downstream syncs. Views Read-only projections used when the sync should expose a curated shape rather than raw tables. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Primary and Foreign Keys Constraints used to identify records and preserve relational integrity in syncs. Rows and columns Standard relational records with typed columns; primary keys anchor upserts. Primary and Foreign Keys is specific to Amazon Aurora and Rows and columns to Azure SQL Database — each maps to any object or custom field on the other side.
Read Replicas Reader endpoints that syncs can target to keep load off the writer. Stored procedures Existing business logic that some teams invoke on write instead of direct table inserts. Read Replicas is specific to Amazon Aurora and Stored procedures to Azure SQL Database — each maps to any object or custom field on the other side.
Databases Logical databases within a cluster that scope a sync connection. Change tracking / CDC tables System-maintained change records used to drive incremental sync. Databases is specific to Amazon Aurora and Change tracking / CDC tables to Azure SQL Database — each maps to any object or custom field on the other side.

How changes propagate between Amazon Aurora and Azure SQL Database

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.

Amazon Aurora Azure SQL Database Sub-second propagation

DetectionChanges in Amazon Aurora are captured at the source via change data capture — no polling loop against its API. Log-based CDC: binlog on MySQL-compatible clusters, logical replication/decoding on PostgreSQL-compatible clusters.

DeliveryEach detected change is applied to Azure SQL Database as a row-level write, with types converted between the two schemas.

Azure SQL Database Amazon Aurora Sub-second propagation

DetectionChanges in Azure SQL Database are captured at the source via change data capture — no polling loop against its API. Change data capture or change tracking, both supported on Azure SQL Database.

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

Rate-limit considerations

  • Amazon Aurora: No API rate limits for wire-protocol access; throughput is bounded by instance class and connection limits.
