GoodData-MongoDB BI Connector Integration Details

When setting up direct data distribution from your MongoDB database through the MongoDB Connector for BI, pay attention to the considerations and best practices listed in this article.

This article is applicable to all use cases of GoodData and MySQL integration:

• Integrate a Data Source for a Data Warehouse (a getting-started guide based on sample data)
• Integrate Data Warehouses Directly to GoodData based on an Existing LDM

Ports Used

You can use any port from within the range of 1024-65535.

User Access Rights

We recommend that you grant the following access rights to the user who is referenced in Data Sources:

The following template can used to create a user:

db.createUser(
  {
    user: "<username>",
    pwd: "<password>",
    roles: [ { role: "read", db: "<dbname>" } ]
  }
 )

The following template can be used to update a user:

db.grantRolesToUser(
   "<username>",
   [ { role: "read", db: "<dbname>" } ]
)

Data Types

When generating the GoodData logical data model (LDM), your MongoDB Connector for BI automatically converts your data to a type that is supported by your connector. This data is then converted to a format that the LDM supports. If you want to prevent automatic changes, update the schema manually. For more information on MongoDB BI Connector file formats, see the MongoDB documentation for their Document Relational Definition Language.
