Why teams connect Amazon Redshift and Citus

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

Common use cases

  • Publish finance rollups computed in Redshift back to spreadsheets or operational tools.
  • Feed customer 360 tables built in Redshift to support and success platforms.
  • 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 Amazon Redshift as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in Amazon Redshift 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 Amazon Redshift and Citus

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.

Amazon Redshift objects Citus objects
Databases Top-level containers within a cluster or serverless workgroup. Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables.
Schemas Namespaces used to organize synced tables and control grants. Schemas Standard Postgres namespaces used to scope what a sync user can read and write.
Tables Columnar tables used as sync destinations for SaaS and database data. Views Curated projections over distributed data, often used as read-only sync sources.
Views SQL views readable as modeled sources for reverse syncs. Sequences Key generators that matter when external writes must not collide with application inserts.
Materialized Views Precomputed results that downstream syncs can read for performance. Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets.
External Tables (Spectrum) S3-backed tables queryable through Redshift, readable in syncs. Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables.

How the Amazon Redshift and Citus connectors work

Amazon Redshift

Integration surface
SQL over JDBC/ODBC (PostgreSQL-derived protocol); Redshift Data API over HTTPS
Authentication
Database credentials or IAM-based authentication
Change detection
Polling or query-based diffing; Redshift does not expose a transaction log for external CDC consumers
Capabilities
read · write
Rate limits
Bounded by cluster or serverless capacity and concurrency settings rather than API quotas

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
