Why teams connect Azure Cosmos DB and Materialize

Connect Azure Cosmos DB and Materialize 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 Materialize, 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 Materialize in real time, and result tables in Materialize sync back into Azure Cosmos DB, with schema and type mapping between the two systems handled for you.

Common use cases

  • Bridge streaming sources and non-streaming destinations by materializing joins across both.
  • Sync operational CRM or ERP data into Materialize so real-time views stay current without batch loads.
  • Mirror Cosmos DB items into Postgres so teams can query operational data with standard SQL.
  • Two-way sync between a Cosmos DB-backed product catalog and a PIM or commerce platform.

Operational data in the warehouse, minus the pipeline

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

Serve warehouse results at database speed

Aggregates or model outputs computed in Materialize sync into Azure Cosmos DB, 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.

What you can sync between Azure Cosmos DB and Materialize

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.

Azure Cosmos DB objects Materialize objects
Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed. Materialized Views Incrementally maintained query results that syncs read as continuously up-to-date datasets.
Partition keys Determine data distribution and must be included on writes for the sync to route items correctly. Sinks Outbound connections that emit view changes to Kafka topics.
Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync. Indexes In-memory arrangements that make view reads fast for serving workloads.
Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation. Clusters Compute pools that isolate ingestion, view maintenance, and serving.
Databases Top-level namespaces that scope containers and throughput provisioning. Connections & Secrets Stored credentials and endpoints used by sources and sinks.
Containers The unit of partitioning and throughput; each container maps to a synced collection. Schemas & Databases Namespaces that organize objects a sync targets.
