Why teams connect Snowflake and StarRocks

Keep tables consistent across Snowflake and StarRocks, 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 StarRocks 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 Feed finance reconciliation models from ERP data landed in Snowflake on a continuous basis
  • 02 Land CRM and ERP records in Snowflake continuously so BI reflects business systems without nightly batch ETL
  • 03 Serve customer-facing analytics from SaaS data synced into one analytical store
  • 04 Consolidate several sources into StarRocks as the query layer while Stacksync handles movement

Common sync patterns

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.

Consolidation after M&A

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

What you can sync between Snowflake and StarRocks

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 StarRocks objects How this pairing syncs
Databases Top-level containers that scope which data a sync can touch. Databases Top-level namespaces addressed exactly as in MySQL clients. 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 Defined with a table model (Primary Key, Unique Key, Aggregate, Duplicate Key) that determines update behavior. 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 for shaping analytical reads. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Materialized Views Precomputed results synced outward for low-latency reads. Materialized views Automatically maintained rollups used to accelerate queries on synced data. 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 organize synced tables. Columns Columnar storage with types mapped from source systems during sync. Schemas is specific to Snowflake and Columns to StarRocks — 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. Partitions Time or range partitions that scope loads and retention. Streams is specific to Snowflake and Partitions to StarRocks — each maps to any object or custom field on the other side.

How changes propagate between Snowflake and StarRocks

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

StarRocks Snowflake Interval-based propagation

DetectionStacksync polls StarRocks for changes on an incremental schedule, reading only records changed since the previous pass. Query-based polling when reading.

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.
  • StarRocks: Ingestion throughput is bounded by cluster resources rather than API quotas.
