Why teams connect Apache Pinot and Azure Cosmos DB

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

Common use cases

  • Serve user-facing analytics from Pinot while syncing daily rollups to finance and ops tools.
  • Keep upsert-enabled real-time tables aligned with mutable operational records streamed from source systems.
  • 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.

Operational data in the warehouse, minus the pipeline

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

Serve warehouse results at database speed

Aggregates or model outputs computed in Apache Pinot 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 Apache Pinot 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.

Apache Pinot objects Azure Cosmos DB objects
Tenants Logical groupings that isolate workloads on shared clusters. Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed.
Tables The queryable unit, defined as offline, real-time, or hybrid; the main read target. Partition keys Determine data distribution and must be included on writes for the sync to route items correctly.
Schemas Column definitions (dimensions, metrics, time columns) mapped during integration setup. Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync.
Segments Immutable data files that batch ingestion uploads and the cluster serves. Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation.
Real-time Tables Tables fed continuously from streams like Kafka, including upsert-enabled tables. Databases Top-level namespaces that scope containers and throughput provisioning.
Offline Tables Batch-loaded tables merged with real-time data at query time. Containers The unit of partitioning and throughput; each container maps to a synced collection.

How the Apache Pinot and Azure Cosmos DB connectors work

Apache Pinot

Integration surface
REST API (SQL queries via the broker; administration via the controller); JDBC client available
Authentication
Deployment-dependent: HTTP basic authentication or token-based auth where enabled
Change detection
Not applicable for reads out (polling by time column); data enters Pinot via streaming ingestion or segment upload, not row-level writes
Capabilities
read · write
Rate limits
No fixed API quotas; query throughput depends on broker and server sizing

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
