Why teams connect Citus and Greenplum

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

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

Common use cases

  • Keep Greenplum and a cloud warehouse in sync during a migration so both platforms serve consistent data.
  • Feed BI reporting by syncing curated Greenplum views to downstream tools on a schedule.
  • Use a Citus cluster as the scalable operational store behind a customer-facing app while syncing summaries back to internal tools.
  • Consolidate per-tenant rows from distributed tables into per-customer reporting databases.

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 Greenplum and keep Citus focused on its operational workload.

Operational data in the warehouse, minus the pipeline

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

What you can sync between Citus and Greenplum

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.

Citus objects Greenplum objects
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Rows Read and written by key; distribution keys determine where rows live.
Views Curated projections over distributed data, often used as read-only sync sources. Databases Top-level containers that scope a sync connection.
Sequences Key generators that matter when external writes must not collide with application inserts. Schemas Namespace tables and control which objects a sync can see.
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Tables Heap or append-optimized tables mapped directly to sync targets.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Partitions Large tables are commonly partitioned by date, which shapes incremental reads.
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Views Read-only projections used to shape data before syncing it out.

Trading partners

EDI

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

How the Citus and Greenplum connectors work

Citus

Integration surface
PostgreSQL wire protocol; any standard Postgres driver connects to the coordinator node
Authentication
Database credentials (standard PostgreSQL authentication; managed deployments add cloud IAM options)
Change detection
PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres
Capabilities
read · write · CDC

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.
