Why teams connect Amazon Redshift and Azure Cosmos DB

Connect Azure Cosmos DB and Amazon Redshift 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 Azure Cosmos DB's rows in Amazon Redshift, 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 Azure Cosmos DB where the services that read from it get them at normal query latency.

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

Common use cases

  • Feed customer 360 tables built in Redshift to support and success platforms.
  • Centralize CRM, ERP, and product data in Redshift so analysts join it with warehouse tables.
  • Sync CRM or ERP records into a Cosmos DB container that backs a customer-facing application.
  • Mirror Cosmos DB items into Postgres so teams can query operational data with standard SQL.

Offload heavy reads

Point analytical queries at the synced copy in Amazon Redshift and keep Azure Cosmos DB focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from Azure Cosmos DB land in Amazon Redshift as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

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

What you can sync between Amazon Redshift and Azure Cosmos 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 Redshift objects Azure Cosmos DB objects
External Tables (Spectrum) S3-backed tables queryable through Redshift, readable in syncs. Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed.
Stored Procedures SQL procedures sometimes invoked around load steps. Partition keys Determine data distribution and must be included on writes for the sync to route items correctly.
Users and Groups Principals used to grant a sync connection scoped access. Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync.
Databases Top-level containers within a cluster or serverless workgroup. Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation.
Schemas Namespaces used to organize synced tables and control grants. Databases Top-level namespaces that scope containers and throughput provisioning.
Tables Columnar tables used as sync destinations for SaaS and database data. Containers The unit of partitioning and throughput; each container maps to a synced collection.

How the Amazon Redshift and Azure Cosmos DB connectors work

Amazon Redshift

Integration surface
SQL over JDBC/ODBC (PostgreSQL-derived protocol); Redshift Data API over HTTPS
Authentication
Database credentials or IAM-based authentication
Change detection
Polling or query-based diffing; Redshift does not expose a transaction log for external CDC consumers
Capabilities
read · write
Rate limits
Bounded by cluster or serverless capacity and concurrency settings rather than API quotas

Azure Cosmos DB

Integration surface
REST API and SDKs over HTTPS (API for NoSQL, formerly the SQL API); also MongoDB, Cassandra, Gremlin, and Table API surfaces
Authentication
Account keys, resource tokens, or Microsoft Entra ID role-based access
Change detection
Built-in change feed exposing inserts and updates in order within each partition key range
Capabilities
read · write · CDC
