Why teams connect Amazon Aurora and Dynamo DB

Keep Amazon Aurora and Dynamo DB 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 Dynamo DB 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

  • Two-way sync between Aurora application tables and a CRM so product data and account data stay consistent.
  • Stream row-level changes from Aurora into a warehouse for near-real-time analytics without batch exports.
  • Mirror SaaS objects into DynamoDB items to serve low-latency lookups from production services.
  • Consolidate multi-region Global Tables data into a single reporting store.

Cross-engine sync

Keep the same dataset live in both Amazon Aurora and Dynamo DB, 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 Amazon Aurora and Dynamo DB

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 Dynamo DB objects
Databases Logical databases within a cluster that scope a sync connection. Tables The top-level containers a sync targets; each table is addressed independently.
Schemas Namespaces (PostgreSQL) or database-level grouping (MySQL) used in table selection. Items Schemaless records keyed by partition (and optional sort) key, mapped to rows or SaaS objects in syncs.
Tables Relational tables synced bi-directionally at row level. Attributes Per-item fields, including nested maps and lists, flattened or mapped during sync.
Views Read-only query-backed sources for downstream syncs. Partition and Sort Keys The primary key pair used as the match key for bi-directional sync.
Materialized Views Precomputed result sets (PostgreSQL-compatible clusters) readable as sources. Global Secondary Indexes Alternate access paths used when sync queries filter on non-key attributes.
Columns and Data Types Standard MySQL or PostgreSQL types mapped during field mapping. DynamoDB Streams Ordered item-level change records consumed for incremental sync.

How the Amazon Aurora and Dynamo DB connectors work

Amazon Aurora

Integration surface
MySQL or PostgreSQL wire protocol (SQL); optional RDS Data API over HTTPS
Authentication
Database credentials or IAM database authentication
Change detection
Log-based CDC: binlog on MySQL-compatible clusters, logical replication/decoding on PostgreSQL-compatible clusters; polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits for wire-protocol access; throughput is bounded by instance class and connection limits

Dynamo DB

Integration surface
Proprietary JSON-over-HTTPS API accessed through AWS SDKs; PartiQL supported for SQL-like queries
Authentication
AWS IAM credentials with SigV4 request signing
Change detection
Item-level change streams via DynamoDB Streams or Kinesis Data Streams integration
Capabilities
read · write · CDC
Rate limits
Throughput is governed by the table's provisioned or on-demand capacity mode
How it works

How to connect Amazon Aurora to Dynamo DB — three steps, no code

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
