This workflow demonstrates aggregation pipelines in MongoDB from KNIME. Aggregation usually works in stages of a pipeline. These are the steps which are executed in sequence until a final output is received. For this example workflow, the sample database from MongoDB Atlas, “sample_restaurants” is used to query the collection name “restaurants”. Output for each query is returned as JSON object.
