Why teams connect Azure Cosmos DB and Rockset

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

Common use cases

  • Serve real-time dashboards over CRM and ERP records synced from operational databases.
  • Sync Postgres or DynamoDB tables into collections for low-latency aggregations without loading a batch warehouse.
  • Two-way sync between a Cosmos DB-backed product catalog and a PIM or commerce platform.
  • Consolidate documents from multiple containers into a single reporting store.

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 Rockset 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 Rockset as they change, replacing hand-built CDC and batch extract jobs.

What you can sync between Azure Cosmos DB and Rockset

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 Rockset objects
Containers The unit of partitioning and throughput; each container maps to a synced collection. Documents JSON records addressable by _id, written via the Write API in sync pipelines.
Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed. Workspaces Namespaces that group collections and query lambdas per team or environment.
Partition keys Determine data distribution and must be included on writes for the sync to route items correctly. Query Lambdas Named, parameterized SQL queries invoked over REST to read synced data.
Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync. Aliases Stable names that point at collections, used to swap datasets without changing queries.
Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation. Integrations Managed source connections (databases, streams, object storage) feeding collections.
Databases Top-level namespaces that scope containers and throughput provisioning. Virtual Instances Isolated compute units that separate ingest from query workloads.
