Why teams connect SQL Server and Vertica

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

Common use cases

  • Push segments or aggregates computed in Vertica back into operational tools such as a CRM.
  • Consolidate data from multiple operational databases into Vertica schemas for enterprise BI.
  • Expose SaaS records as SQL Server tables that existing SSRS reports and internal apps can query
  • Mirror on-premises ERP data held in SQL Server into cloud CRM and support systems

Offload heavy reads

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

Operational data in the warehouse, minus the pipeline

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

Serve warehouse results at database speed

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

What you can sync between SQL Server and Vertica

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.

SQL Server objects Vertica objects
Schemas Namespaces (dbo and custom) used to organize synced tables. Views Logical views used to shape reads for downstream consumers.
Tables The primary sync target; rows map to records in connected systems. Flex Tables Schema-flexible tables for semi-structured JSON data landed before modeling.
Views Read-side projections used as outbound sync sources. External Tables Data queried in place on files or object storage without loading.
Columns Field-level mapping targets with T-SQL types. Schemas Namespaces used to organize synced datasets by domain or source.
Primary and Unique Keys Match keys for idempotent upserts and conflict handling. Tables Columnar tables; the primary read and write targets for syncs.
CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers. Projections Sorted, encoded physical copies of table data that the optimizer selects at query time; they affect load and query behavior rather than being addressed directly.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between SQL Server and Vertica.

How the SQL Server and Vertica connectors work

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
SQL Server setup guide

Vertica

Integration surface
SQL over JDBC, ODBC, and ADO.NET drivers
Authentication
Database credentials, with LDAP, Kerberos, and OAuth options in enterprise deployments
Change detection
No exposed transaction-log CDC; polling on timestamp or epoch columns
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by cluster resources, and bulk COPY is preferred over row-by-row writes.
How it works

How to connect SQL Server to Vertica — three steps, no code

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
