Why teams connect Materialize and OpenSearch

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

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

Common use cases

  • Sync operational CRM or ERP data into Materialize so real-time views stay current without batch loads.
  • Read computed view results back into a CRM or application database as derived fields.
  • Stream CRM records such as accounts, contacts, and tickets into OpenSearch to power internal search across customer data.
  • Sync product catalogs from an ERP or database into the indexes that back storefront search.

Serve warehouse results at database speed

Aggregates or model outputs computed in Materialize sync into OpenSearch, 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 OpenSearch focused on its operational workload.

What you can sync between Materialize and OpenSearch

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.

Materialize objects OpenSearch objects
Indexes In-memory arrangements that make view reads fast for serving workloads. Index templates Mapping and settings presets applied to new indexes a sync creates
Clusters Compute pools that isolate ingestion, view maintenance, and serving. Ingest pipelines Server-side processors that transform documents as they are written
Connections & Secrets Stored credentials and endpoints used by sources and sinks. Data streams Append-oriented time-series storage for logs and events pushed from source systems
Schemas & Databases Namespaces that organize objects a sync targets. Snapshots Backup artifacts, relevant when reseeding an index from a repository
Tables User-managed tables that accept INSERT/UPDATE/DELETE from sync pipelines. Indexes The core container; synced records land in indexes with defined mappings
Sources Ingestion points (Kafka, Postgres CDC, MySQL CDC, webhook) that feed external data into Materialize. Documents JSON records written via the index and bulk APIs and read via search queries
