Why teams connect Azure Synapse Analytics and Snowflake

Keep tables consistent across Azure Synapse Analytics 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 Azure Synapse Analytics 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

  • Load CRM and ERP records into Synapse dedicated SQL pool tables for enterprise reporting.
  • Publish warehouse aggregates (account health scores, LTV) from Synapse back into operational tools like a CRM.
  • Feed finance reconciliation models from ERP data landed in Snowflake on a continuous basis
  • Land CRM and ERP records in Snowflake continuously so BI reflects business systems without nightly batch ETL

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 Azure Synapse Analytics 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.

Azure Synapse Analytics objects Snowflake objects
Tables (dedicated SQL pool) Distributed warehouse tables that serve as sync destinations for analytics workloads. Tables The main landing and activation target for synced records.
External tables Tables over files in the data lake, queried through serverless SQL and often read-only in syncs. Views Modeled projections used as the source side of outbound syncs.
Views Curated projections used when downstream tools should not read base tables directly. Materialized Views Precomputed results synced outward for low-latency reads.
Schemas Namespaces that separate staging, integration, and presentation layers. Streams Row-level change records on a table, consumed to process deltas instead of full scans.
Materialized views Precomputed aggregates that speed reads of frequently synced result sets. Stages File staging areas used for bulk loads into synced tables.
SQL pools Dedicated or serverless compute contexts that determine how and where queries run. Tasks Scheduled SQL used to transform synced data after it lands.

How the Azure Synapse Analytics and Snowflake connectors work

Azure Synapse Analytics

Integration surface
SQL wire protocol (TDS) with T-SQL for SQL pools; additional Spark and pipeline surfaces exist but syncs use the SQL endpoint
Authentication
SQL authentication or Microsoft Entra ID
Change detection
Polling on watermark columns; Synapse SQL pools do not expose log-based CDC for downstream consumers
Capabilities
read · write

Snowflake

Integration surface
SQL via JDBC/ODBC and native drivers, plus the Snowflake SQL REST API
Authentication
Dedicated Snowflake service user + role with RSA key-pair authentication (Stacksync-provided public key), created via a setup script requiring SECURITY_ADMIN and ACCOUNTADMIN roles
Change detection
Not explicitly stated; the setup script grants "create stream" on synced schemas (Snowflake streams), but the docs do not name the change-capture mechanism
Capabilities
read · write · CDC
Rate limits
No conventional API rate limits; cost and throughput are governed by virtual warehouse size and running time
