Why teams connect Apache Kylin and PostgreSQL

Flow Apache Kylin data into PostgreSQL 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 PostgreSQL, so PostgreSQL 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 PostgreSQL'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 PostgreSQL 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.
  • Feed reporting and BI from a continuously synced Postgres replica instead of scheduled ETL scripts
  • Expose SaaS objects (CRM contacts, ERP invoices, support tickets) as Postgres tables that internal tools can query and join

Offload heavy reads

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

Operational data in the warehouse, minus the pipeline

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

What you can sync between Apache Kylin and PostgreSQL

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 PostgreSQL objects
Source Tables Hive or other upstream tables that builds read from. Views Read-side projections used to expose joined or filtered data to a sync.
Segments Time-ranged build units that partition pre-computed data. Materialized Views Precomputed result sets synced outward on a refresh schedule.
Build Jobs Batch jobs that compute or refresh segments, monitored via the REST API. Schemas Namespaces that scope which tables a sync reads and writes.
Projects Top-level workspaces that group models, tables, and jobs. Columns Field-level mapping targets; types are mapped to the connected system's field types.
Models Star-schema definitions over source tables that determine what can be queried. Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution.
Cubes / Indexes Pre-computed aggregate structures that answer queries at low latency. JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata.

How the Apache Kylin and PostgreSQL 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

PostgreSQL

Integration surface
SQL wire protocol (PostgreSQL frontend/backend protocol)
Authentication
Database credentials (connection string or parameters), with optional SSL root certificate upload and optional SSH tunnel (SSH user + host); a least-privilege DB user
Change detection
Logical replication (wal_level = logical) for change data capture via the "Postgres" connector; database triggers (TRIGGER grant + stacksync_logging schema) via the trigger-based "Postgres Heroku" connector where
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by connection limits, instance resources, and replication slot throughput
