Why teams connect Greenplum and SQL Server

Connect SQL Server and Greenplum 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 Greenplum, 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 Greenplum in real time, and result tables in Greenplum sync back into SQL Server, with schema and type mapping between the two systems handled for you.

Common use cases

  • Feed BI reporting by syncing curated Greenplum views to downstream tools on a schedule.
  • Consolidate data from multiple source systems into partitioned Greenplum fact tables.
  • Consolidate branch or plant databases into a single operational SQL Server hub
  • Bi-directional sync between SQL Server rows and CRM objects so .NET line-of-business apps and sales tools share one dataset

Serve warehouse results at database speed

Aggregates or model outputs computed in Greenplum sync into SQL Server, 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 Greenplum and keep SQL Server focused on its operational workload.

What you can sync between Greenplum 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.

Greenplum objects SQL Server objects
Rows Read and written by key; distribution keys determine where rows live. Views Read-side projections used as outbound sync sources.
Databases Top-level containers that scope a sync connection. Columns Field-level mapping targets with T-SQL types.
Schemas Namespace tables and control which objects a sync can see. Primary and Unique Keys Match keys for idempotent upserts and conflict handling.
Tables Heap or append-optimized tables mapped directly to sync targets. CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers.
Partitions Large tables are commonly partitioned by date, which shapes incremental reads. Stored Procedures T-SQL logic that can validate or post-process synced rows.
Views Read-only projections used to shape data before syncing it out. Databases Instance-level databases that scope a sync's reads and writes.

How the Greenplum and SQL Server connectors work

Greenplum

Integration surface
PostgreSQL wire protocol (libpq), plus JDBC/ODBC drivers
Authentication
Database credentials
Change detection
Polling with timestamp or key-based cursors; Greenplum does not expose logical-decoding CDC
Capabilities
read · write
Rate limits
Bounded by cluster resources and concurrency settings rather than an API quota.

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
