Why teams connect CockroachDB and Materialize

Connect CockroachDB and Materialize 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 CockroachDB's rows in Materialize, 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 CockroachDB where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in CockroachDB sync into Materialize in real time, and result tables in Materialize sync back into CockroachDB, with schema and type mapping between the two systems handled for you.

Common use cases

  • Drive alerting and operational tooling from SUBSCRIBE change streams instead of scheduled queries.
  • Maintain real-time inventory, usage, or account-health counters consumed by customer-facing applications.
  • 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.

Serve warehouse results at database speed

Aggregates or model outputs computed in Materialize sync into CockroachDB, 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.

Offload heavy reads

Point analytical queries at the synced copy in Materialize and keep CockroachDB focused on its operational workload.

What you can sync between CockroachDB and Materialize

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.

CockroachDB objects Materialize objects
Tables The core read/write target; rows sync bi-directionally with SaaS objects or other databases. Sinks Outbound connections that emit view changes to Kafka topics.
Views Read-only projections used as curated sync sources. Indexes In-memory arrangements that make view reads fast for serving workloads.
Indexes Secondary indexes that keep sync lookup queries fast on key columns. Clusters Compute pools that isolate ingestion, view maintenance, and serving.
Sequences ID generators that matter when writes originate from an external system. Connections & Secrets Stored credentials and endpoints used by sources and sinks.
Changefeeds Built-in CDC streams that emit row-level changes to external sinks. Schemas & Databases Namespaces that organize objects a sync targets.
Databases Logical containers a sync connects to, addressed like PostgreSQL databases. Tables User-managed tables that accept INSERT/UPDATE/DELETE from sync pipelines.
