Two-way sync
Changes in Materialize or OpenSearch instantly reflect in both systems. No stale data, no manual imports.
Keep Materialize and OpenSearch in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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.
Aggregates or model outputs computed in Materialize sync into OpenSearch, where whatever reads from that database gets them without querying the warehouse.
Because changes stream continuously, analysts query current data instead of waiting for last night's load.
Point analytical queries at the synced copy in Materialize and keep OpenSearch focused on its operational workload.
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 |
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Materialize–OpenSearch connection.
Changes in Materialize or OpenSearch instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Materialize or OpenSearch data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Materialize or OpenSearch record.
Track your Materialize ⇄ OpenSearch sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Materialize and OpenSearch.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Materialize and OpenSearch with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Materialize and OpenSearch objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Materialize and OpenSearch: authenticate both systems, choose the objects to sync (such as Materialize's Indexes and Clusters), map fields visually, and changes propagate both ways in milliseconds — no code required.
Common patterns for Materialize and OpenSearch: Serve warehouse results at database speed; Fresh analytics without loading windows; Offload heavy reads. Aggregates or model outputs computed in Materialize sync into OpenSearch, where whatever reads from that database gets them without querying the warehouse.
Materialize: PostgreSQL wire protocol (SQL). Authentication: Database credentials (username/password; app passwords in the managed cloud service). OpenSearch: REST API over HTTP(S) with JSON payloads. Authentication: Basic authentication with the security plugin, or AWS IAM request signing on Amazon OpenSearch Service. Stacksync manages authentication, retries, and rate limits on both sides.
Materialize: Views are maintained incrementally as data arrives rather than recomputed at query time, which is what makes reads consistently fresh. OpenSearch: OpenSearch exposes no built-in change feed, so it usually serves as a sync destination with sources pushing documents in through the bulk API. Stacksync's field mapping accounts for these differences between Materialize and OpenSearch without custom code.
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Materialize and OpenSearch records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Materialize and OpenSearch connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Materialize–OpenSearch integration in-house.
As a data company, we understand the importance of keeping your data secure. Stacksync is built with security best practices to keep your data safe at every layer, and is DPF-certified for US, EU, UK and CH data transfers.
Let your users access Stacksync from your centralized user management systems. Works with Okta, Azure, Google SSO and more.
