MongoDB ​

MongoDB is a popular, open source NoSQL database known for its flexibility, scalability, and wide adoption in a variety of applications.

Bruin supports MongoDB as a source for Ingestr assets, and you can use it to ingest data from MongoDB into your data warehouse.

In order to set up MongoDB connection, you need to add a configuration item in the .bruin.yml file and in asset file.

Follow the steps below to correctly set up MongoDB as a data source and run ingestion.

Step 1: Add a connection to .bruin.yml file ​

To connect to MongoDB, you need to add a configuration item to the connections section of the .bruin.yml file. This configuration must comply with the following schema:

yaml
    connections:
      mongo:
        - name: "localMongo"
          username: "testUser"
          password: "testPass123"
          host: "localhost"
          port: 27018
          database: "testDB"
  • name: The name to identify this MongoDB connection
  • username: The MongoDB username with access to the database
  • password: The password for the specified username
  • host: The host address of the MongoDB server (e.g., localhost or an IP address)
  • port: The port number the database server is listening on (default: 27017)
  • database: The name of the database to connect to

Step 2: Create an asset file for data ingestion ​

To ingest data from MongoDB, you need to create an asset configuration file. This file defines the data flow from the source to the destination. Create a YAML file (e.g., mongo_ingestion.yml) inside the assets folder and add the following content:

yaml
name: public.mongo
type: ingestr
connection: postgres

parameters:
  source_connection: localMongo
  source_table: 'users.details'

  destination: postgres
  • name: The name of the asset.
  • type: Specifies the type of the asset. Set this to ingestr to use the ingestr data pipeline.
  • connection: This is the destination connection, which defines where the data should be stored. For example: postgres indicates that the ingested data will be stored in a Postgres database.
  • source_connection: The name of the MongoDB connection defined in .bruin.yml.
  • source_table: The name of the data table in MongoDB that you want to ingest.

Step 3: Run asset to ingest data ​

bruin run assets/mongo_ingestion.yml

As a result of this command, Bruin will ingest data from the given MongoDB table into your Postgres database.
