MongoDB auto increment

MongoDB does not have out-of-the-box auto-increment functionality, like SQL databases. By default, it uses the 12-byte ObjectId for the _id field as the primary key to uniquely identify the documents. However, there may be scenarios where we may want the _id field to have some auto-incremented value other than the ObjectId MongoDB에서 auto-increment를 제공하지 않는 이유 같은 이유. MongoDB에서 _id 필드나 다른 어떤 필드를 위한 auto-increment 패턴을 사용할 필요가 없다. auto-increment 패턴을 사용하면 데이터베이스에 많은 documents가 있을 경우 확장성이 떨어진다

MongoDB Auto Increment Sequence Overview. Unlike SQL databases, the auto-increment feature is not supported in MongoDB. MongoDB does provide the ObjectId, which can be used as a primary key- a value that makes each document unique within a collection. This functionality is useful to a certain degree, but not sufficient for real-time operations How MongoDB Auto Increment Sequence Works?
