Why teams connect Citus and Vertica

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

Common use cases

  • Sync CRM accounts and opportunities into Vertica to join with large-scale behavioral or telemetry data.
  • Land ERP transactions in Vertica for finance analytics without maintaining hand-built ETL jobs.
  • Use a Citus cluster as the scalable operational store behind a customer-facing app while syncing summaries back to internal tools.
  • Consolidate per-tenant rows from distributed tables into per-customer reporting databases.

Operational data in the warehouse, minus the pipeline

Rows from Citus 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 Citus, 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 Citus 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.

Citus objects Vertica objects
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. 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.
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Views Logical views used to shape reads for downstream consumers.
Views Curated projections over distributed data, often used as read-only sync sources. Flex Tables Schema-flexible tables for semi-structured JSON data landed before modeling.
Sequences Key generators that matter when external writes must not collide with application inserts. External Tables Data queried in place on files or object storage without loading.
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Schemas Namespaces used to organize synced datasets by domain or source.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Tables Columnar tables; the primary read and write targets for syncs.

Trading partners

EDI

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

How the Citus and Vertica connectors work

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
Capabilities
read · write · CDC

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.
