Why teams connect Greenplum and MongoDB

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

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

Common use cases

  • Publish segments, scores, and aggregates computed in Greenplum back into business tools where teams act on them.
  • Keep Greenplum and a cloud warehouse in sync during a migration so both platforms serve consistent data.
  • Sync MongoDB collections with a CRM so customer documents written by the application appear as CRM records, and CRM edits flow back as document updates.
  • Replicate operational MongoDB data into a relational database, flattening nested documents into normalized tables for SQL reporting.

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 MongoDB focused on its operational workload.

Operational data in the warehouse, minus the pipeline

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

What you can sync between Greenplum and MongoDB

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 MongoDB objects
Databases Top-level containers that scope a sync connection. Collections The table-like sync unit; each collection maps to a table or object in the paired system.
Schemas Namespace tables and control which objects a sync can see. Documents BSON records created, updated, and deleted during syncs, keyed by _id.
Tables Heap or append-optimized tables mapped directly to sync targets. Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets.
Partitions Large tables are commonly partitioned by date, which shapes incremental reads. Indexes Keep lookups by sync key fast on large collections.
Views Read-only projections used to shape data before syncing it out. Views Read-only aggregation-defined sources for filtered sync datasets.
External tables Reference external files for bulk load paths alongside row-level syncs. Change streams The oplog-backed event feed that powers real-time change capture.

Workflow automation

Trigger automated workflows whenever Greenplum or MongoDB data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single Greenplum or MongoDB record.

Observability

Monitoring

Track your Greenplum ⇄ MongoDB sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between Greenplum and MongoDB.

How the Greenplum and MongoDB 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.

MongoDB

Integration surface
MongoDB wire protocol via official drivers; Atlas additionally offers an administration REST API for cluster management
Authentication
Database credentials (username/password) or TLS/SSL X.509 certificate (.pem upload), entered individually or via a MongoDB connection string (SRV or standard); Stacksync IP allowlisting required
Change detection
MongoDB oplog and change streams (requires the database to run as a replica set — even single-node); Stacksync leverages these built-in tools to track changes in real time
Capabilities
read · write · CDC

How it works

How to connect Greenplum to MongoDB — three steps, no code

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.

  1. 01

    Connect your apps

    Authenticate Greenplum and MongoDB with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
