Why teams connect Apache Kylin and Couchbase

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

Common use cases

  • Sync Kylin aggregates into a cloud warehouse to combine them with data Kylin does not cover.
  • Trigger downstream syncs after segment build jobs complete so consumers only read refreshed data.
  • Write cleaned or enriched records from operational databases back into Couchbase collections that applications read.
  • Sync Couchbase JSON documents into Postgres or a warehouse where analysts work with flattened relational tables.

Offload heavy reads

Point analytical queries at the synced copy in Apache Kylin and keep Couchbase focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from Couchbase 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 Couchbase, where whatever reads from that database gets them without querying the warehouse.

What you can sync between Apache Kylin and Couchbase

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 Couchbase objects
Models Star-schema definitions over source tables that determine what can be queried. Scopes Namespaces inside a bucket used to group collections, similar to schemas.
Cubes / Indexes Pre-computed aggregate structures that answer queries at low latency. Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables.
Source Tables Hive or other upstream tables that builds read from. JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs.
Segments Time-ranged build units that partition pre-computed data. Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient.
Build Jobs Batch jobs that compute or refresh segments, monitored via the REST API. XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster.
Projects Top-level workspaces that group models, tables, and jobs. Full-text search indexes Search indexes over documents, relevant when syncing searchable content.

How the Apache Kylin and Couchbase 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

Couchbase

Integration surface
SQL++ (N1QL) query service, key-value SDK APIs, and REST management APIs
Authentication
Database credentials with role-based access control, typically over TLS
Change detection
Database Change Protocol (DCP) streams document mutations; SQL++ polling on document fields as an alternative
Capabilities
read · write · CDC
Rate limits
Throughput is bounded by cluster sizing rather than API rate limits
