Why teams connect Citus and Exasol

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

Common use cases

  • Keep dimension tables such as customers and products aligned with the systems of record.
  • Load CRM and ERP records into Exasol tables on a schedule so analysts query fresh operational data.
  • 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.

Operational data in the warehouse, minus the pipeline

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

Serve warehouse results at database speed

Aggregates or model outputs computed in Exasol 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 Exasol

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 Exasol objects
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. UDF scripts In-database functions that can transform synced data after load.
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Users and roles Grant read/write access for the dedicated integration account.
Views Curated projections over distributed data, often used as read-only sync sources. Schemas Namespaces that group the tables a sync reads from or writes into.
Sequences Key generators that matter when external writes must not collide with application inserts. Tables Primary sync target; columnar relational tables written with standard SQL.
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Views Read-only query surfaces often used as curated sources for reverse ETL.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Virtual schemas Federated views over external sources; useful for deciding what needs physical replication.

How the Citus and Exasol 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

Exasol

Integration surface
SQL over JDBC/ODBC drivers and a WebSocket-based client protocol
Authentication
Database credentials (username and password)
Change detection
Polling with timestamp or key columns; Exasol does not expose a transaction-log change feed to clients
Capabilities
read · write
Rate limits
No API quota; concurrency is bounded by cluster resources and session limits
