Why teams connect Greenplum and OpenSearch

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

Common use cases

  • Load operational data from CRMs, ERPs, and production databases into Greenplum for MPP analytics.
  • Publish segments, scores, and aggregates computed in Greenplum back into business tools where teams act on them.
  • 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.

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 Greenplum and keep OpenSearch focused on its operational workload.

Operational data in the warehouse, minus the pipeline

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

What you can sync between Greenplum 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.

Greenplum objects OpenSearch objects
Tables Heap or append-optimized tables mapped directly to sync targets. Ingest pipelines Server-side processors that transform documents as they are written
Partitions Large tables are commonly partitioned by date, which shapes incremental reads. Data streams Append-oriented time-series storage for logs and events pushed from source systems
Views Read-only projections used to shape data before syncing it out. Snapshots Backup artifacts, relevant when reseeding an index from a repository
External tables Reference external files for bulk load paths alongside row-level syncs. Indexes The core container; synced records land in indexes with defined mappings
Rows Read and written by key; distribution keys determine where rows live. Documents JSON records written via the index and bulk APIs and read via search queries
Databases Top-level containers that scope a sync connection. Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills

How the Greenplum and OpenSearch connectors work

Greenplum

Integration surface
PostgreSQL wire protocol (libpq), plus JDBC/ODBC drivers
Authentication
Database credentials
Change detection
Polling with timestamp or key-based cursors; Greenplum does not expose logical-decoding CDC
Capabilities
read · write
Rate limits
Bounded by cluster resources and concurrency settings rather than an API quota.

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
