Why teams connect Citus and CockroachDB

Keep Citus and CockroachDB synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between Citus and CockroachDB continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • 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.
  • Consolidate data from several SaaS tools into one distributed SQL store that survives zone failures.
  • Write application events from CockroachDB back to CRM fields to give go-to-market teams product context.

Cross-engine sync

Keep the same dataset live in both Citus and CockroachDB, so each workload runs on the engine that suits it.

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

What you can sync between Citus and CockroachDB

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 CockroachDB objects
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Schemas Namespaces within a database used to isolate synced tables from application tables.
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Tables The core read/write target; rows sync bi-directionally with SaaS objects or other databases.
Views Curated projections over distributed data, often used as read-only sync sources. Views Read-only projections used as curated sync sources.
Sequences Key generators that matter when external writes must not collide with application inserts. Indexes Secondary indexes that keep sync lookup queries fast on key columns.
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Sequences ID generators that matter when writes originate from an external system.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Changefeeds Built-in CDC streams that emit row-level changes to external sinks.

How the Citus and CockroachDB 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

CockroachDB

Integration surface
SQL wire protocol (PostgreSQL-compatible)
Authentication
Database credentials with TLS; client certificates or SCRAM password auth
Change detection
CDC via changefeeds, which stream row-level changes; polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits in the SaaS sense; throughput is bounded by cluster capacity
