Why teams connect Apache Doris and PostgreSQL

Connect PostgreSQL and Apache Doris 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 Doris, 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 Doris in real time, and result tables in Apache Doris sync back into PostgreSQL, with schema and type mapping between the two systems handled for you.

Common use cases

  • Consolidate event and transactional data from multiple sources into one real-time OLAP layer.
  • Land CRM and operational database records in Doris for low-latency dashboards over fresh data.
  • Let an application write to its own database and have those rows appear as records in business systems in near real time
  • Consolidate data from several microservice databases into one operational Postgres store

Offload heavy reads

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

Operational data in the warehouse, minus the pipeline

Rows from PostgreSQL land in Apache Doris as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in Apache Doris sync into PostgreSQL, where whatever reads from that database gets them without querying the warehouse.

What you can sync between Apache Doris 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 Doris objects PostgreSQL objects
Partitions Range or list partitions that bound incremental loads. JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata.
Materialized Views Precomputed views readable for downstream syncs and BI. Sequences Generate surrogate keys for rows created by inbound syncs.
Users and Roles Principals used to grant the sync connection scoped access. Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields.
Databases Logical containers that scope connections and grants. Tables The primary sync target; rows map one-to-one to records in connected SaaS systems.
Tables Columnar tables in one of Doris's table models, used as sync destinations. Views Read-side projections used to expose joined or filtered data to a sync.
Unique Key Tables Tables supporting primary-key upserts, the natural target for row-level syncs. Materialized Views Precomputed result sets synced outward on a refresh schedule.
What ships with Apache Doris ⇄ PostgreSQL

At scale

Event queues

Handle millions of events per minute without losing a single Apache Doris or PostgreSQL record.

Observability

Monitoring

Track your Apache Doris ⇄ PostgreSQL sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between Apache Doris and PostgreSQL.

How the Apache Doris and PostgreSQL connectors work

Apache Doris

Integration surface
MySQL wire protocol for SQL access; HTTP APIs (such as Stream Load) for bulk ingestion
Authentication
Database credentials
Change detection
Polling on partition or timestamp columns for reads; ingestion into Doris is push-based via load jobs
Capabilities
read · write
Rate limits
No API quotas; load throughput depends on cluster resources and load-job configuration

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

How it works

How to connect Apache Doris to PostgreSQL — three steps, no code

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

  1. 01

    Connect your apps

    Authenticate Apache Doris and PostgreSQL with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
