Why teams connect Exasol and MongoDB
Connect MongoDB and Exasol 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 Exasol, 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 Exasol in real time, and result tables in Exasol sync back into MongoDB, with schema and type mapping between the two systems handled for you.
Common use cases
- Consolidate data from multiple operational databases into Exasol as the central analytics layer.
- Keep dimension tables such as customers and products aligned with the systems of record.
- Replicate operational MongoDB data into a relational database, flattening nested documents into normalized tables for SQL reporting.
- Capture change stream events and propagate them to SaaS tools in near real time instead of running batch exports.
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 Exasol and keep MongoDB focused on its operational workload.
Operational data in the warehouse, minus the pipeline
Rows from MongoDB land in Exasol as they change, replacing hand-built CDC and batch extract jobs.
What you can sync between Exasol 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.
| Exasol objects | MongoDB objects | |
|---|---|---|
| Users and roles Grant read/write access for the dedicated integration account. | Documents BSON records created, updated, and deleted during syncs, keyed by _id. | |
| Schemas Namespaces that group the tables a sync reads from or writes into. | Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets. | |
| Tables Primary sync target; columnar relational tables written with standard SQL. | Indexes Keep lookups by sync key fast on large collections. | |
| Views Read-only query surfaces often used as curated sources for reverse ETL. | Views Read-only aggregation-defined sources for filtered sync datasets. | |
| Virtual schemas Federated views over external sources; useful for deciding what needs physical replication. | Change streams The oplog-backed event feed that powers real-time change capture. | |
| UDF scripts In-database functions that can transform synced data after load. | GridFS files Chunked file storage whose metadata can be referenced by synced documents. |

How the Exasol and MongoDB connectors work
Exasol
- Integration surface
- SQL over JDBC/ODBC drivers and a WebSocket-based client protocol
- Authentication
- Database credentials (username and password)
- Change detection
- Polling with timestamp or key columns; Exasol does not expose a transaction-log change feed to clients
- Capabilities
- read · write
- Rate limits
- No API quota; concurrency is bounded by cluster resources and session limits
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

FAQ
Exasol and MongoDB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Exasol and MongoDB: authenticate both systems, choose the objects to sync (such as Exasol's Users and roles and Schemas), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Exasol: SQL over JDBC/ODBC drivers and a WebSocket-based client protocol. Authentication: Database credentials (username and password). MongoDB: 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. Stacksync manages authentication, retries, and rate limits on both sides.
-
Exasol: Virtual schemas let Exasol query external sources in place, which affects whether data needs to be physically synced at all. MongoDB: Change streams expose ordered change events with resume tokens, so an interrupted sync can pick up exactly where it stopped without a full re-read. Stacksync's field mapping accounts for these differences between Exasol and MongoDB 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 Exasol and MongoDB records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Exasol and MongoDB connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Exasol–MongoDB integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Exasol and MongoDB. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
