Why teams connect OpenSearch and StarRocks

Connect OpenSearch and StarRocks 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 StarRocks, 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 StarRocks in real time, and result tables in StarRocks sync back into OpenSearch, with schema and type mapping between the two systems handled for you.

Common use cases

  • Consolidate several sources into StarRocks as the query layer while Stacksync handles movement
  • Land CRM and ERP records into StarRocks to serve low-latency operational dashboards
  • 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.

Offload heavy reads

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

Operational data in the warehouse, minus the pipeline

Rows from OpenSearch land in StarRocks as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in StarRocks sync into OpenSearch, where whatever reads from that database gets them without querying the warehouse.

What you can sync between OpenSearch and StarRocks

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.

OpenSearch objects StarRocks objects
Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills Databases Top-level namespaces addressed exactly as in MySQL clients.
Index templates Mapping and settings presets applied to new indexes a sync creates Tables Defined with a table model (Primary Key, Unique Key, Aggregate, Duplicate Key) that determines update behavior.
Ingest pipelines Server-side processors that transform documents as they are written Materialized views Automatically maintained rollups used to accelerate queries on synced data.
Data streams Append-oriented time-series storage for logs and events pushed from source systems Views Logical views for shaping analytical reads.
Snapshots Backup artifacts, relevant when reseeding an index from a repository Partitions Time or range partitions that scope loads and retention.
Indexes The core container; synced records land in indexes with defined mappings Columns Columnar storage with types mapped from source systems during sync.

How the OpenSearch and StarRocks connectors work

OpenSearch

Integration surface
REST API over HTTP(S) with JSON payloads
Authentication
basic authentication with the security plugin, or AWS IAM request signing on Amazon OpenSearch Service
Change detection
no native change feed; reads rely on queries with scroll or point-in-time polling
Capabilities
read · write
Rate limits
throughput bounded by cluster sizing rather than fixed API quotas

StarRocks

Integration surface
MySQL wire protocol for SQL; HTTP-based Stream Load API for ingestion
Authentication
Database credentials (MySQL-compatible username/password)
Change detection
Query-based polling when reading; StarRocks is most often the destination side of a sync
Capabilities
read · write
Rate limits
Ingestion throughput is bounded by cluster resources rather than API quotas
