Is your experience with MongoDB just hearsay or have you actually worked with it?

I have worked with MongoDB in several projects, where I used it as the main data storage for Java applications. I used the MongoDB driver for Java, created queries using BSON, built aggregations, and indexed collections to optimize performance. For example, I implemented storing documents with a dynamic schema, which allowed quick adaptation to changing requirements without complex database migrations.

An example of connecting to MongoDB in Java using MongoClient:

import com.mongodb.client.MongoClients;
import com.mongodb.client.MongoClient;
import com.mongodb.client.MongoDatabase;

public class MongoExample {
    public static void main(String[] args) {
        try (MongoClient mongoClient = MongoClients.create("mongodb://localhost:27017")) {
            MongoDatabase database = mongoClient.getDatabase("mydb");
            System.out.println("Connected to database: " + database.getName());
        }
    }
}
