What is a MongoDB ObjectId?
A MongoDB ObjectId is a 12-byte identifier used as the default primary key for MongoDB documents. The ObjectId encodes a 4-byte timestamp, a 5-byte random value (machine + process), and a 3-byte incrementing counter. This structure ensures uniqueness across distributed systems and allows you to extract the creation time from the ObjectId. ObjectIds are compact, sortable by creation time, and widely used in NoSQL databases. However, they do reveal the creation time and some machine information.
Format
ObjectId consists of a 4-byte timestamp, 3-byte machine identifier, 2-byte process ID, and 3-byte counter
