Why teams connect Azure Synapse Analytics and SQL Server

Connect SQL Server and Azure Synapse Analytics with one live, two-way sync: operational rows flow into the warehouse, and computed results flow back where systems can read them fast.

Operational databases and analytical warehouses want the same data at different moments. Analysts want SQL Server's rows in Azure Synapse Analytics, current and joinable, without a change-data-capture pipeline to maintain. Engineers want the outputs of warehouse work, such as aggregates, features, and segments, available in SQL Server where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in SQL Server sync into Azure Synapse Analytics in real time, and result tables in Azure Synapse Analytics sync back into SQL Server, with schema and type mapping between the two systems handled for you.

Common use cases

  • Publish warehouse aggregates (account health scores, LTV) from Synapse back into operational tools like a CRM.
  • Sync curated Synapse views into an operational Postgres or Azure SQL database that applications can query cheaply.
  • Bi-directional sync between SQL Server rows and CRM objects so .NET line-of-business apps and sales tools share one dataset
  • Expose SaaS records as SQL Server tables that existing SSRS reports and internal apps can query

Offload heavy reads

Point analytical queries at the synced copy in Azure Synapse Analytics and keep SQL Server focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from SQL Server land in Azure Synapse Analytics as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in Azure Synapse Analytics sync into SQL Server, where whatever reads from that database gets them without querying the warehouse.

What you can sync between Azure Synapse Analytics and SQL Server

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 SQL Server objects
SQL pools Dedicated or serverless compute contexts that determine how and where queries run. Schemas Namespaces (dbo and custom) used to organize synced tables.
Tables (dedicated SQL pool) Distributed warehouse tables that serve as sync destinations for analytics workloads. Tables The primary sync target; rows map to records in connected systems.
External tables Tables over files in the data lake, queried through serverless SQL and often read-only in syncs. Views Read-side projections used as outbound sync sources.
Views Curated projections used when downstream tools should not read base tables directly. Columns Field-level mapping targets with T-SQL types.
Schemas Namespaces that separate staging, integration, and presentation layers. Primary and Unique Keys Match keys for idempotent upserts and conflict handling.
Materialized views Precomputed aggregates that speed reads of frequently synced result sets. CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers.

How the Azure Synapse Analytics and SQL Server 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

SQL Server

Integration surface
SQL over the TDS wire protocol (Tabular Data Stream), via ODBC/JDBC/ADO.NET drivers
Authentication
Database credentials entered as a connection string or as parameters (host/user/password) in the Create New Sync page
Change detection
SQL Server Native Change Data Capture (CDC); a DBA runs a one-time setup script with sysadmin privileges to enable CDC and create Stacksync wrapper procedures
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput depends on instance resources, licensing tier, and connection limits
