Why teams connect Apache Kylin and Azure Cosmos DB

Flow Apache Kylin data into Azure Cosmos DB in real time — no exports, no schedulers, no custom scripts.

Apache Kylin is a read-only source: Stacksync reads its data in real time and delivers it into Azure Cosmos DB, so Azure Cosmos DB always reflects the current state of Apache Kylin — without exports, scripts, or schedulers.

Operational databases and analytical warehouses want the same data at different moments. Analysts want Azure Cosmos DB's rows in Apache Kylin, 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.

Common use cases

  • Expose Kylin query results to operational dashboards without granting access to the underlying Hadoop data.
  • Sync Kylin aggregates into a cloud warehouse to combine them with data Kylin does not cover.
  • Stream operational documents from Cosmos DB into a SQL warehouse via the change feed for analytics without hitting request-unit budgets with full scans.
  • Sync CRM or ERP records into a Cosmos DB container that backs a customer-facing application.

Operational data in the warehouse, minus the pipeline

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

Serve warehouse results at database speed

Aggregates or model outputs computed in Apache Kylin 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 Kylin 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 Kylin objects Azure Cosmos DB objects
Segments Time-ranged build units that partition pre-computed data. Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation.
Build Jobs Batch jobs that compute or refresh segments, monitored via the REST API. Databases Top-level namespaces that scope containers and throughput provisioning.
Projects Top-level workspaces that group models, tables, and jobs. Containers The unit of partitioning and throughput; each container maps to a synced collection.
Models Star-schema definitions over source tables that determine what can be queried. Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed.
Cubes / Indexes Pre-computed aggregate structures that answer queries at low latency. Partition keys Determine data distribution and must be included on writes for the sync to route items correctly.
Source Tables Hive or other upstream tables that builds read from. Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync.

How the Apache Kylin and Azure Cosmos DB connectors work

Apache Kylin

Integration surface
SQL over JDBC/ODBC plus a REST API for queries and administration
Authentication
Username/password (HTTP basic authentication on the REST API)
Change detection
Not applicable for row-level capture; data freshness follows segment build and refresh jobs, so integrations poll query results
Capabilities
read
Rate limits
No fixed API quotas; query capacity depends on the deployment and pre-computed index coverage

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
