Why teams connect Snowflake and Vertica

Keep tables consistent across Snowflake and Vertica, 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 Snowflake and Vertica 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 Activate modeled Snowflake tables by syncing scores and attributes back into CRM fields sales can act on
  • 02 Keep a customer 360 table aligned with its source systems in both directions instead of one-way reverse ETL
  • 03 Push segments or aggregates computed in Vertica back into operational tools such as a CRM.
  • 04 Consolidate data from multiple operational databases into Vertica schemas for enterprise BI.

Common sync patterns

Shared datasets across teams

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

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.

What you can sync between Snowflake and Vertica

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.

Snowflake objects Vertica objects How this pairing syncs
Schemas Namespaces within a database used to organize synced tables. Schemas Namespaces used to organize synced datasets by domain or source. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables The main landing and activation target for synced records. Tables Columnar tables; the primary read and write targets for syncs. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Modeled projections used as the source side of outbound syncs. Views Logical views used to shape reads for downstream consumers. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Databases Top-level containers that scope which data a sync can touch. Flex Tables Schema-flexible tables for semi-structured JSON data landed before modeling. Databases is specific to Snowflake and Flex Tables to Vertica — each maps to any object or custom field on the other side.
Materialized Views Precomputed results synced outward for low-latency reads. External Tables Data queried in place on files or object storage without loading. Materialized Views is specific to Snowflake and External Tables to Vertica — each maps to any object or custom field on the other side.
Streams Row-level change records on a table, consumed to process deltas instead of full scans. Projections Sorted, encoded physical copies of table data that the optimizer selects at query time; they affect load and query behavior rather than being addressed directly. Streams is specific to Snowflake and Projections to Vertica — each maps to any object or custom field on the other side.

How changes propagate between Snowflake and Vertica

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.

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

Vertica Snowflake Interval-based propagation

DetectionStacksync polls Vertica for changes on an incremental schedule, reading only records changed since the previous pass. No exposed transaction-log CDC.

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

Rate-limit considerations

  • Snowflake: No conventional API rate limits; cost and throughput are governed by virtual warehouse size and running time.
  • Vertica: No API rate limits; throughput is bounded by cluster resources, and bulk COPY is preferred over row-by-row writes.
