Introduction

This document aims to guide users through the process of creating a MongoDB instance, and performing basic database operations.

How to Work with MongoDB?

Step 1: Establish a Connection

Make sure you possess appropriate credentials for establishing a connection with a MongoDB database server.

Step 2: Choose the River Mode

Once you have successfully established a connection to MongoDB, select the River mode to load data into a Target. There are 3 available options for you to choose from:

Please Note:

By clicking on the highlighted modes below, you will be taken to a relevant page that offers a comprehensive explanation and presents a Product Tour example showcasing the available features in MongoDB.

  • Multi-Tables : Simultaneously load multiple tables from MySQL to your desired Target.

    • Standard Extraction - This River mode maps, transforms, and loads data from multiple tables into a unified schema. It uses SQL queries for transformations and can be scheduled or manually triggered.
    • Change Streams - This mode monitors Source database logs, capturing and transforming changes in real-time. This ensures minimal data loss and low latency transfer when loading the transformed data into the target database, keeping it in sync with the Source.
  • Legacy River: Select a sole Source table for loading into a Target.

Please Note:
Incrementing columns with the '$' operator is not supported in Multi-Tables and Legacy River modes
