Why teams connect Azure Synapse Analytics and Citus

Connect Citus 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 Citus'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 Citus where the services that read from it get them at normal query latency.

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

Common use cases

  • Consolidate SaaS data alongside lake data so analysts join both through one SQL surface.
  • Load CRM and ERP records into Synapse dedicated SQL pool tables for enterprise reporting.
  • Write CRM or billing records into reference tables so distributed queries can join operational context locally on every node.
  • Use a Citus cluster as the scalable operational store behind a customer-facing app while syncing summaries back to internal tools.

Fresh analytics without loading windows

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

Offload heavy reads

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

Operational data in the warehouse, minus the pipeline

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

What you can sync between Azure Synapse Analytics and Citus

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 Citus objects
External tables Tables over files in the data lake, queried through serverless SQL and often read-only in syncs. Schemas Standard Postgres namespaces used to scope what a sync user can read and write.
Views Curated projections used when downstream tools should not read base tables directly. Views Curated projections over distributed data, often used as read-only sync sources.
Schemas Namespaces that separate staging, integration, and presentation layers. Sequences Key generators that matter when external writes must not collide with application inserts.
Materialized views Precomputed aggregates that speed reads of frequently synced result sets. Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets.
SQL pools Dedicated or serverless compute contexts that determine how and where queries run. Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables.
Tables (dedicated SQL pool) Distributed warehouse tables that serve as sync destinations for analytics workloads. Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables.

How the Azure Synapse Analytics and Citus 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

Citus

Integration surface
PostgreSQL wire protocol; any standard Postgres driver connects to the coordinator node
Authentication
Database credentials (standard PostgreSQL authentication; managed deployments add cloud IAM options)
Change detection
PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres
