Why teams connect Apache Pinot and PostgreSQL

Connect PostgreSQL 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 PostgreSQL'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 PostgreSQL where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in PostgreSQL sync into Apache Pinot in real time, and result tables in Apache Pinot sync back into PostgreSQL, with schema and type mapping between the two systems handled for you.

Common use cases

  • Sync Pinot aggregates into a warehouse to join low-latency metrics with modeled historical data.
  • Serve user-facing analytics from Pinot while syncing daily rollups to finance and ops tools.
  • 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

Serve warehouse results at database speed

Aggregates or model outputs computed in Apache Pinot sync into PostgreSQL, 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.

Offload heavy reads

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

What you can sync between Apache Pinot 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 Pinot objects PostgreSQL objects
Schemas Column definitions (dimensions, metrics, time columns) mapped during integration setup. JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata.
Segments Immutable data files that batch ingestion uploads and the cluster serves. Sequences Generate surrogate keys for rows created by inbound syncs.
Real-time Tables Tables fed continuously from streams like Kafka, including upsert-enabled tables. Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields.
Offline Tables Batch-loaded tables merged with real-time data at query time. Tables The primary sync target; rows map one-to-one to records in connected SaaS systems.
Indexes Inverted, range, and star-tree indexes that determine which sync queries run at low latency. Views Read-side projections used to expose joined or filtered data to a sync.
Tenants Logical groupings that isolate workloads on shared clusters. Materialized Views Precomputed result sets synced outward on a refresh schedule.

How the Apache Pinot and PostgreSQL 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

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
