stages
MongoDB Connector for BI 2.1.0¶
- Provides substantial performance improvements for some common
JOIN
scenarios. - Pushes
$match
stages earlier in the aggregation pipeline to improve to index utilization. - Pushes down more SQL functions and operators to the aggregation pipeline.

keyword in date arithmetic.
MongoDB Connector for BI 2.0.0¶
Released Nov 29, 2016
Improved Server-Side Execution¶
The MongoDB Connector for BI delivers significant performance and scalability improvements by moving as much execution as possible to the underlying MongoDB instance. Pushing execution down to the server reduces network latency and reduces bandwidth consumption.
This approach also reduces memory and CPU consumption in the MongoDB Connector for BI itself.
Pass-through Authentication¶
The user authentication process is now passed through the MongoDB Connector for BI to the underlying MongoDB instance. Users now authenticate as a user already created within MongoDB.
Simplified Architecture¶
The MongoDB Connector for BI package is now trimmed down from four separate components to two:
mongodrdl
- This tool connects to a MongoDB instance and generates a Document-Relational Definition Language (DRDL) file, which maps a given collection shape to relational schema.
mongosqld
Once installed and run as a daemon,
mongosqld
responds to SQL queries, requests for DB information, and schema from the requesting BI tool via the MySQL wire protocol.mongosqld
requires at least one Document Relational Definition Language file to start. You will need to have defined your schema withmongodrdl
before startingmongosqld
.
SQL Compatibility¶
MongoDB Connector for BI Version 2.x is compatible with SQL-99 SELECT statements, and uses the MySQL wire protocol.
