Why teams connect Greenplum and MotherDuck

Keep tables consistent across Greenplum and MotherDuck, for a migration, a multi-warehouse stack, or a dataset two platforms both need.

Companies end up with two warehouses for practical reasons: a migration in progress, teams that standardized on different platforms, an acquisition, or tools that only connect to one of them. The result is the same dataset maintained twice, with duplicated pipelines and numbers that almost match.

Stacksync syncs tables between Greenplum and MotherDuck continuously, in either or both directions. Rows changed on one platform appear on the other within seconds, with schema and type mapping handled, so both warehouses answer questions with the same data.

Common use cases

  • Consolidate data from multiple source systems into partitioned Greenplum fact tables.
  • Load operational data from CRMs, ERPs, and production databases into Greenplum for MPP analytics.
  • Sync modeled MotherDuck tables outward to operational tools for activation
  • Share curated, synced datasets with other teams through read-only database shares

Consolidation after M&A

Bring the acquired company's warehouse data across continuously instead of through one-off dumps.

Migration without a big bang

When one platform is replacing the other, keep tables mirrored while workloads move over gradually, and cut over with nothing to backfill.

Serve tools that only connect to one platform

Mirror the datasets a BI tool, notebook, or application needs onto the platform it can actually reach.

What you can sync between Greenplum and MotherDuck

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 MotherDuck objects
Partitions Large tables are commonly partitioned by date, which shapes incremental reads. Views Modeled projections used as outbound sync sources.
Views Read-only projections used to shape data before syncing it out. Database Shares Read-only copies of a database shared with other users or teams.
External tables Reference external files for bulk load paths alongside row-level syncs. Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries.
Rows Read and written by key; distribution keys determine where rows live. Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes.
Databases Top-level containers that scope a sync connection. Schemas Namespaces within a database used to organize synced tables.
Schemas Namespace tables and control which objects a sync can see. Tables The main landing target for synced records and source for analysis.

Rate limits
Bounded by cluster resources and concurrency settings rather than an API quota.

MotherDuck

Integration surface
SQL through DuckDB clients and drivers using a MotherDuck (md:) connection
Authentication
Access token created in MotherDuck (Settings > General > Create Token), pasted into Stacksync; database name and schema configurable if not using defaults
Change detection
Polling; no log-based CDC or webhook surface is exposed
Capabilities
read · write
Rate limits
Subject to the platform's compute and concurrency limits rather than per-request API rate limits
