Why teams connect Apache Kylin and MongoDB

Flow Apache Kylin data into MongoDB 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 MongoDB, so MongoDB 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 MongoDB'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 MongoDB where the services that read from it get them at normal query latency.

Common use cases

  • Trigger downstream syncs after segment build jobs complete so consumers only read refreshed data.
  • Read pre-aggregated metrics from Kylin and sync them into CRM fields or planning spreadsheets on a schedule.
  • Consolidate documents from multiple clusters or tenants into a single warehouse-facing store.
  • Sync MongoDB collections with a CRM so customer documents written by the application appear as CRM records, and CRM edits flow back as document updates.

Operational data in the warehouse, minus the pipeline

Rows from MongoDB 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 MongoDB, 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 MongoDB

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 MongoDB objects
Projects Top-level workspaces that group models, tables, and jobs. Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets.
Models Star-schema definitions over source tables that determine what can be queried. Indexes Keep lookups by sync key fast on large collections.
Cubes / Indexes Pre-computed aggregate structures that answer queries at low latency. Views Read-only aggregation-defined sources for filtered sync datasets.
Source Tables Hive or other upstream tables that builds read from. Change streams The oplog-backed event feed that powers real-time change capture.
Segments Time-ranged build units that partition pre-computed data. GridFS files Chunked file storage whose metadata can be referenced by synced documents.
Build Jobs Batch jobs that compute or refresh segments, monitored via the REST API. Databases Logical groupings of collections that scope a sync connection.

How the Apache Kylin and MongoDB 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

MongoDB

Integration surface
MongoDB wire protocol via official drivers; Atlas additionally offers an administration REST API for cluster management
Authentication
Database credentials (username/password) or TLS/SSL X.509 certificate (.pem upload), entered individually or via a MongoDB connection string (SRV or standard); Stacksync IP allowlisting required
Change detection
MongoDB oplog and change streams (requires the database to run as a replica set — even single-node); Stacksync leverages these built-in tools to track changes in real time
Capabilities
read · write · CDC
