Why teams connect Greenplum and PostgreSQL

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

Common use cases

  • Load operational data from CRMs, ERPs, and production databases into Greenplum for MPP analytics.
  • Publish segments, scores, and aggregates computed in Greenplum back into business tools where teams act on them.
  • 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 Greenplum and keep PostgreSQL focused on its operational workload.

Operational data in the warehouse, minus the pipeline

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

Serve warehouse results at database speed

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

What you can sync between Greenplum 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.

Greenplum objects PostgreSQL objects
Partitions Large tables are commonly partitioned by date, which shapes incremental reads. Sequences Generate surrogate keys for rows created by inbound syncs.
Views Read-only projections used to shape data before syncing it out. Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields.
External tables Reference external files for bulk load paths alongside row-level syncs. Tables The primary sync target; rows map one-to-one to records in connected SaaS systems.
Rows Read and written by key; distribution keys determine where rows live. Views Read-side projections used to expose joined or filtered data to a sync.
Databases Top-level containers that scope a sync connection. Materialized Views Precomputed result sets synced outward on a refresh schedule.
Schemas Namespace tables and control which objects a sync can see. Schemas Namespaces that scope which tables a sync reads and writes.
What ships with Greenplum ⇄ PostgreSQL

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

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

Real-time

Two-way sync

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

No-code + pro-code

Workflow automation

Trigger automated workflows whenever Greenplum or PostgreSQL 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 Greenplum or PostgreSQL record.

Observability

Monitoring

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

Trading partners

EDI

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

How the Greenplum and PostgreSQL connectors work

Greenplum

Integration surface
PostgreSQL wire protocol (libpq), plus JDBC/ODBC drivers
Authentication
Database credentials
Change detection
Polling with timestamp or key-based cursors; Greenplum does not expose logical-decoding CDC
Capabilities
read · write
Rate limits
Bounded by cluster resources and concurrency settings rather than an API quota.

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 Greenplum 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 Greenplum 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.

    Choose tables

    Pick the Greenplum and PostgreSQL objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
