Do i need to close connection of mongodb

Question

With the help of programming, can you tell me if I need to close the connection to MongoDB?

Answer 1

Yes, it's important to manage MongoDB connections properly to ensure efficient resource usage and prevent potential issues.

In most applications, especially those using connection pooling, you don't need to close individual database connections after each operation. Instead, you should close the main MongoClient instance when your application shuts down. This practice helps in releasing all underlying resources, including sockets and background monitoring threads.

You can use the close() method or a try-with-resources statement to ensure the MongoClient is closed properly in Java:

try (MongoClient mongoClient = MongoClients.create("mongodb://localhost/")) {

    MongoDatabase database = mongoClient.getDatabase("test");

    MongoCollection<Document> collection = database.getCollection("testColl");

    Document doc = collection.find(new Document()).first();

    System.out.println(doc.toJson());

}
