Why teams connect Amazon RDS and Azure Synapse Analytics

Connect Amazon RDS and Azure Synapse Analytics 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 RDS's rows in Azure Synapse Analytics, 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 RDS 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 RDS sync into Azure Synapse Analytics in real time, and result tables in Azure Synapse Analytics sync back into Amazon RDS, with schema and type mapping between the two systems handled for you.

Common use cases

  • Publish warehouse aggregates (account health scores, LTV) from Synapse back into operational tools like a CRM.
  • Sync curated Synapse views into an operational Postgres or Azure SQL database that applications can query cheaply.
  • Sync master data (customers, products, pricing) from an ERP into the RDS databases that power customer-facing apps
  • Use a read replica as the sync source to keep change capture load off the primary instance

Serve warehouse results at database speed

Aggregates or model outputs computed in Azure Synapse Analytics sync into Amazon RDS, where whatever reads from that database gets them without querying the warehouse.

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 Azure Synapse Analytics and keep Amazon RDS focused on its operational workload.

What you can sync between Amazon RDS and Azure Synapse Analytics

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 RDS objects Azure Synapse Analytics objects
Read Replicas Low-impact read endpoints often used as the source side of a sync. SQL pools Dedicated or serverless compute contexts that determine how and where queries run.
Stored Procedures Engine-specific logic that can react to synced rows. Tables (dedicated SQL pool) Distributed warehouse tables that serve as sync destinations for analytics workloads.
Databases Engine-level databases on the instance that scope a sync's reads and writes. External tables Tables over files in the data lake, queried through serverless SQL and often read-only in syncs.
Schemas Namespaces within a database used to isolate synced tables. Views Curated projections used when downstream tools should not read base tables directly.
Tables The core sync target; rows map to records in connected SaaS systems. Schemas Namespaces that separate staging, integration, and presentation layers.
Views Read-side projections exposed to outbound syncs. Materialized views Precomputed aggregates that speed reads of frequently synced result sets.

How the Amazon RDS and Azure Synapse Analytics connectors work

Amazon RDS

Integration surface
SQL wire protocol of the chosen engine (PostgreSQL, MySQL, MariaDB, SQL Server, Oracle)
Authentication
Database credentials over SSL/TLS, or IAM database authentication on supported engines
Change detection
Engine-native log-based CDC: MySQL/MariaDB binlog, PostgreSQL logical replication, SQL Server CDC; enabled through RDS parameter groups, with polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput depends on instance class, storage IOPS, and connection limits

Azure Synapse Analytics

Integration surface
SQL wire protocol (TDS) with T-SQL for SQL pools; additional Spark and pipeline surfaces exist but syncs use the SQL endpoint
Authentication
SQL authentication or Microsoft Entra ID
Change detection
Polling on watermark columns; Synapse SQL pools do not expose log-based CDC for downstream consumers
Capabilities
