Why teams connect Azure Synapse Analytics and Postgres Heroku

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

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

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.
  • Expose CRM objects as Postgres tables the Heroku application can query and join directly
  • Sync Heroku Postgres into a warehouse for reporting without running ETL dynos

Serve warehouse results at database speed

Aggregates or model outputs computed in Azure Synapse Analytics sync into Postgres Heroku, 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.

Offload heavy reads

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

What you can sync between Azure Synapse Analytics and Postgres Heroku

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 Postgres Heroku objects
Tables (dedicated SQL pool) Distributed warehouse tables that serve as sync destinations for analytics workloads. Sequences Generate surrogate keys for rows created by inbound syncs.
External tables Tables over files in the data lake, queried through serverless SQL and often read-only in syncs. Follower Databases Heroku-managed read replicas usable as low-impact sync sources.
Views Curated projections used when downstream tools should not read base tables directly. Tables Standard Postgres tables; the primary two-way sync target for app data.
Schemas Namespaces that separate staging, integration, and presentation layers. Views Read-side projections exposed to outbound syncs.
Materialized views Precomputed aggregates that speed reads of frequently synced result sets. Materialized Views Precomputed result sets synced outward on refresh.
SQL pools Dedicated or serverless compute contexts that determine how and where queries run. Schemas Namespaces that scope which tables a sync reads and writes.

How the Azure Synapse Analytics and Postgres Heroku 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

Postgres Heroku

Integration surface
SQL wire protocol (standard PostgreSQL)
Authentication
Database credentials from the Heroku DATABASE_URL config var; SSL required
Change detection
Trigger-based capture or polling in most configurations; log-based logical replication availability depends on plan and Heroku's managed server settings
Capabilities
read · write
Rate limits
No API rate limits; connection counts and performance are bounded by the Heroku Postgres plan
