Why teams connect Amazon Aurora and MotherDuck

Connect Amazon Aurora and MotherDuck with one live, two-way sync: operational rows flow into the warehouse, and computed results flow back where systems can read them fast.

Operational databases and analytical warehouses want the same data at different moments. Analysts want Amazon Aurora's rows in MotherDuck, current and joinable, without a change-data-capture pipeline to maintain. Engineers want the outputs of warehouse work, such as aggregates, features, and segments, available in Amazon Aurora where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in Amazon Aurora sync into MotherDuck in real time, and result tables in MotherDuck sync back into Amazon Aurora, with schema and type mapping between the two systems handled for you.

Common use cases

  • Sync modeled MotherDuck tables outward to operational tools for activation
  • Share curated, synced datasets with other teams through read-only database shares
  • Write enriched or scored records from analytics pipelines back into the Aurora tables that power an application.
  • Offload sync reads to Aurora reader endpoints to avoid load on the writer instance.

Fresh analytics without loading windows

Because changes stream continuously, analysts query current data instead of waiting for last night's load.

Offload heavy reads

Point analytical queries at the synced copy in MotherDuck and keep Amazon Aurora focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from Amazon Aurora land in MotherDuck as they change, replacing hand-built CDC and batch extract jobs.

What you can sync between Amazon Aurora and MotherDuck

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 MotherDuck objects
Schemas Namespaces (PostgreSQL) or database-level grouping (MySQL) used in table selection. Tables The main landing target for synced records and source for analysis.
Tables Relational tables synced bi-directionally at row level. Views Modeled projections used as outbound sync sources.
Views Read-only query-backed sources for downstream syncs. Database Shares Read-only copies of a database shared with other users or teams.
Materialized Views Precomputed result sets (PostgreSQL-compatible clusters) readable as sources. Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries.
Columns and Data Types Standard MySQL or PostgreSQL types mapped during field mapping. Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes.
Primary and Foreign Keys Constraints used to identify records and preserve relational integrity in syncs. Schemas Namespaces within a database used to organize synced tables.

How the Amazon Aurora and MotherDuck 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

MotherDuck

Integration surface
SQL through DuckDB clients and drivers using a MotherDuck (md:) connection
Authentication
Access token created in MotherDuck (Settings > General > Create Token), pasted into Stacksync; database name and schema configurable if not using defaults
Change detection
Polling; no log-based CDC or webhook surface is exposed
Capabilities
read · write
Rate limits
Subject to the platform's compute and concurrency limits rather than per-request API rate limits
