Why teams connect Amazon RDS and Materialize

Connect Amazon RDS 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 Amazon RDS'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 Amazon RDS where the services that read from it get them at normal query latency.

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

Common use cases

  • Read computed view results back into a CRM or application database as derived fields.
  • Drive alerting and operational tooling from SUBSCRIBE change streams instead of scheduled queries.
  • Sync master data (customers, products, pricing) from an ERP into the RDS databases that power customer-facing apps
  • Use a read replica as the sync source to keep change capture load off the primary instance

Operational data in the warehouse, minus the pipeline

Rows from Amazon RDS land in Materialize as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in Materialize sync into Amazon RDS, 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 RDS 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.

Amazon RDS objects Materialize objects
Tables The core sync target; rows map to records in connected SaaS systems. Sources Ingestion points (Kafka, Postgres CDC, MySQL CDC, webhook) that feed external data into Materialize.
Views Read-side projections exposed to outbound syncs. Materialized Views Incrementally maintained query results that syncs read as continuously up-to-date datasets.
Columns Field-level mapping targets, typed per the underlying engine. Sinks Outbound connections that emit view changes to Kafka topics.
Primary and Unique Keys Match keys for idempotent upserts. Indexes In-memory arrangements that make view reads fast for serving workloads.
Read Replicas Low-impact read endpoints often used as the source side of a sync. Clusters Compute pools that isolate ingestion, view maintenance, and serving.
Stored Procedures Engine-specific logic that can react to synced rows. Connections & Secrets Stored credentials and endpoints used by sources and sinks.
