Why teams connect Apache Pinot and MongoDB

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

Common use cases

  • Keep upsert-enabled real-time tables aligned with mutable operational records streamed from source systems.
  • Query per-account usage metrics from Pinot and sync them into CRM fields so sales sees product activity.
  • Capture change stream events and propagate them to SaaS tools in near real time instead of running batch exports.
  • Keep a MongoDB-backed product catalog aligned with an ERP's item master in both directions.

Serve warehouse results at database speed

Aggregates or model outputs computed in Apache Pinot sync into MongoDB, 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 Apache Pinot and keep MongoDB focused on its operational workload.

What you can sync between Apache Pinot 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.

Apache Pinot objects MongoDB objects
Real-time Tables Tables fed continuously from streams like Kafka, including upsert-enabled tables. Indexes Keep lookups by sync key fast on large collections.
Offline Tables Batch-loaded tables merged with real-time data at query time. Views Read-only aggregation-defined sources for filtered sync datasets.
Indexes Inverted, range, and star-tree indexes that determine which sync queries run at low latency. Change streams The oplog-backed event feed that powers real-time change capture.
Tenants Logical groupings that isolate workloads on shared clusters. GridFS files Chunked file storage whose metadata can be referenced by synced documents.
Tables The queryable unit, defined as offline, real-time, or hybrid; the main read target. Databases Logical groupings of collections that scope a sync connection.
Schemas Column definitions (dimensions, metrics, time columns) mapped during integration setup. Collections The table-like sync unit; each collection maps to a table or object in the paired system.

How the Apache Pinot and MongoDB connectors work

Apache Pinot

Integration surface
REST API (SQL queries via the broker; administration via the controller); JDBC client available
Authentication
Deployment-dependent: HTTP basic authentication or token-based auth where enabled
Change detection
Not applicable for reads out (polling by time column); data enters Pinot via streaming ingestion or segment upload, not row-level writes
Capabilities
read · write
Rate limits
No fixed API quotas; query throughput depends on broker and server sizing

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
