Why teams connect Greenplum and Snowflake

Keep tables consistent across Greenplum and Snowflake, 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 Snowflake 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

  • 01 Publish segments, scores, and aggregates computed in Greenplum back into business tools where teams act on them.
  • 02 Keep Greenplum and a cloud warehouse in sync during a migration so both platforms serve consistent data.
  • 03 Land CRM and ERP records in Snowflake continuously so BI reflects business systems without nightly batch ETL
  • 04 Activate modeled Snowflake tables by syncing scores and attributes back into CRM fields sales can act on

Common sync patterns

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.

Shared datasets across teams

Where different teams run different warehouses, sync the curated tables both rely on so their metrics agree by construction.

What you can sync between Greenplum and Snowflake

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 Snowflake objects How this pairing syncs
Databases Top-level containers that scope a sync connection. Databases Top-level containers that scope which data a sync can touch. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Schemas Namespace tables and control which objects a sync can see. Schemas Namespaces within a database used to organize synced tables. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables Heap or append-optimized tables mapped directly to sync targets. Tables The main landing and activation target for synced records. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Read-only projections used to shape data before syncing it out. Views Modeled projections used as the source side of outbound syncs. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Rows Read and written by key; distribution keys determine where rows live. VARIANT Columns Semi-structured JSON payloads stored alongside relational columns. Rows is specific to Greenplum and VARIANT Columns to Snowflake — each maps to any object or custom field on the other side.
Partitions Large tables are commonly partitioned by date, which shapes incremental reads. Virtual Warehouses The compute a sync's queries run on, sized independently of storage. Partitions is specific to Greenplum and Virtual Warehouses to Snowflake — each maps to any object or custom field on the other side.

How changes propagate between Greenplum and Snowflake

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.

Greenplum Snowflake 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 Snowflake as a row-level write, with types converted between the two schemas.

Snowflake Greenplum Sub-second propagation

DetectionChanges in Snowflake are captured at the source via change data capture — no polling loop against its API. The setup script grants "create stream" on synced schemas (Snowflake streams), but the docs do not name the change-capture mechanism.

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

Rate-limit considerations

  • Greenplum: Bounded by cluster resources and concurrency settings rather than an API quota.
  • Snowflake: No conventional API rate limits; cost and throughput are governed by virtual warehouse size and running time.
