Why teams connect Apache Doris and Azure SQL Database

Connect Azure SQL Database and Apache Doris 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 Azure SQL Database's rows in Apache Doris, 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 Azure SQL Database where the services that read from it get them at normal query latency.

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

Common use cases

  • Land CRM and operational database records in Doris for low-latency dashboards over fresh data.
  • Continuously upsert changing records into Unique Key tables so analytics reflect current state rather than append-only history.
  • Replicate Azure SQL tables to a warehouse without building custom CDC pipelines.
  • Consolidate data from several line-of-business apps into one Azure SQL database as an integration hub.

Operational data in the warehouse, minus the pipeline

Rows from Azure SQL Database land in Apache Doris as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

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

Fresh analytics without loading windows

Because changes stream continuously, analysts query current data instead of waiting for last night's load.

What you can sync between Apache Doris and Azure SQL Database

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.

Apache Doris objects Azure SQL Database objects
Materialized Views Precomputed views readable for downstream syncs and BI. Schemas Namespaces that organize tables and control which objects a sync user can reach.
Users and Roles Principals used to grant the sync connection scoped access. Rows and columns Standard relational records with typed columns; primary keys anchor upserts.
Databases Logical containers that scope connections and grants. Stored procedures Existing business logic that some teams invoke on write instead of direct table inserts.
Tables Columnar tables in one of Doris's table models, used as sync destinations. Change tracking / CDC tables System-maintained change records used to drive incremental sync.
Unique Key Tables Tables supporting primary-key upserts, the natural target for row-level syncs. Tables The primary sync target; rows map one-to-one to records in the paired system.
Aggregate Key Tables Tables that pre-aggregate on load, used for metric rollups. Views Read-only projections used when the sync should expose a curated shape rather than raw tables.

How the Apache Doris and Azure SQL Database connectors work

Apache Doris

Integration surface
MySQL wire protocol for SQL access; HTTP APIs (such as Stream Load) for bulk ingestion
Authentication
Database credentials
Change detection
Polling on partition or timestamp columns for reads; ingestion into Doris is push-based via load jobs
Capabilities
read · write
Rate limits
No API quotas; load throughput depends on cluster resources and load-job configuration

Azure SQL Database

Integration surface
SQL wire protocol (TDS), the same protocol as SQL Server; T-SQL over standard drivers
Authentication
SQL authentication (database credentials) or Microsoft Entra ID authentication
Change detection
Change data capture or change tracking, both supported on Azure SQL Database; polling as a fallback
Capabilities
read · write · CDC
