Why teams connect PostgreSQL and StarRocks

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

Common use cases

  • Continuously apply upserts from operational databases into Primary Key tables to keep analytics current
  • Serve customer-facing analytics from SaaS data synced into one analytical store
  • Expose SaaS objects (CRM contacts, ERP invoices, support tickets) as Postgres tables that internal tools can query and join
  • Let an application write to its own database and have those rows appear as records in business systems in near real time

Operational data in the warehouse, minus the pipeline

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

Serve warehouse results at database speed

Aggregates or model outputs computed in StarRocks 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.

What you can sync between PostgreSQL and StarRocks

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.

PostgreSQL objects StarRocks objects
Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields. Tables Defined with a table model (Primary Key, Unique Key, Aggregate, Duplicate Key) that determines update behavior.
Tables The primary sync target; rows map one-to-one to records in connected SaaS systems. Materialized views Automatically maintained rollups used to accelerate queries on synced data.
Views Read-side projections used to expose joined or filtered data to a sync. Views Logical views for shaping analytical reads.
Materialized Views Precomputed result sets synced outward on a refresh schedule. Partitions Time or range partitions that scope loads and retention.
Schemas Namespaces that scope which tables a sync reads and writes. Columns Columnar storage with types mapped from source systems during sync.
Columns Field-level mapping targets; types are mapped to the connected system's field types. Databases Top-level namespaces addressed exactly as in MySQL clients.
What ships with PostgreSQL ⇄ StarRocks

Connect PostgreSQL and StarRocks for flexible, real-time data sync.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every PostgreSQL–StarRocks connection.

Real-time

Two-way sync

Changes in PostgreSQL or StarRocks instantly reflect in both systems. No stale data, no manual imports.

No-code + pro-code

Workflow automation

Trigger automated workflows whenever PostgreSQL or StarRocks data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

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

Observability

Monitoring

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

Trading partners

EDI

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

How the PostgreSQL and StarRocks connectors work

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
PostgreSQL setup guide

StarRocks

Integration surface
MySQL wire protocol for SQL; HTTP-based Stream Load API for ingestion
Authentication
Database credentials (MySQL-compatible username/password)
Change detection
Query-based polling when reading; StarRocks is most often the destination side of a sync
Capabilities
read · write
Rate limits
Ingestion throughput is bounded by cluster resources rather than API quotas
How it works

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