Why teams connect CockroachDB and Greenplum

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

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

Common use cases

  • 01 Feed BI reporting by syncing curated Greenplum views to downstream tools on a schedule.
  • 02 Consolidate data from multiple source systems into partitioned Greenplum fact tables.
  • 03 Use changefeeds to propagate row changes from a multi-region cluster into a warehouse or search index.
  • 04 Keep reference data consistent between CockroachDB and regional application databases.

Common sync patterns

Offload heavy reads

Point analytical queries at the synced copy in Greenplum and keep CockroachDB focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from CockroachDB 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 CockroachDB, where whatever reads from that database gets them without querying the warehouse.

What you can sync between CockroachDB 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.

CockroachDB objects Greenplum objects How this pairing syncs
Databases Logical containers a sync connects to, addressed like PostgreSQL databases. Databases Top-level containers that scope a sync connection. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Schemas Namespaces within a database used to isolate synced tables from application tables. Schemas Namespace tables and control which objects a sync can see. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables The core read/write target; rows sync bi-directionally with SaaS objects or other databases. Tables Heap or append-optimized tables mapped directly to sync targets. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Read-only projections used as curated sync sources. Views Read-only projections used to shape data before syncing it out. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Sequences ID generators that matter when writes originate from an external system. Partitions Large tables are commonly partitioned by date, which shapes incremental reads. Sequences is specific to CockroachDB and Partitions to Greenplum — each maps to any object or custom field on the other side.
Changefeeds Built-in CDC streams that emit row-level changes to external sinks. External tables Reference external files for bulk load paths alongside row-level syncs. Changefeeds is specific to CockroachDB and External tables to Greenplum — each maps to any object or custom field on the other side.

How changes propagate between CockroachDB and Greenplum

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

CockroachDB Greenplum Sub-second propagation

DetectionChanges in CockroachDB are captured at the source via change data capture — no polling loop against its API. CDC via changefeeds, which stream row-level changes.

DeliveryEach detected change is applied to Greenplum as a row-level write, with types converted between the two schemas.

Greenplum CockroachDB Interval-based propagation

DetectionStacksync polls Greenplum for changes on an incremental schedule, reading only records changed since the previous pass. Polling with timestamp or key-based cursors.

DeliveryEach detected change is applied to CockroachDB as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • CockroachDB: No API rate limits in the SaaS sense; throughput is bounded by cluster capacity.
  • Greenplum: Bounded by cluster resources and concurrency settings rather than an API quota.
