How Does The _id Field Work In MongoDB? Have you ever wondered how data is uniquely identified and organized in MongoDB? In this informative video, we'll explain everything you need to know about the id field in MongoDB. We’ll start by discussing what the id field is and why it’s essential for managing documents within a collection. You’ll learn how MongoDB automatically assigns a unique identifier to each document if none is provided, and what makes this identifier so special. We’ll explore the structure of the ObjectId, a 12-byte data type, and how its components—such as timestamp, machine identifier, process ID, and counter—work together to ensure uniqueness across distributed systems. You’ll also discover how you can customize your own id if needed, and why MongoDB enforces the uniqueness rule to prevent conflicts. Additionally, we’ll explain how the id field is automatically indexed, making searches, updates, and deletions faster and more efficient. Understanding how the id field functions is key for backend developers, especially when building APIs that require precise data retrieval or modifications. Knowing that the ObjectId contains creation time information can also help you track when documents were added, without extra effort. Whether working on small projects or large-scale systems, mastering the id field helps keep your data organized and accessible.
