I want to use id(1-n) to record the order of blog posts, and find one on the Internet.Method, by adding a sequence table, but this method has a disadvantage, that is, once one of the articles is deleted, the other id will not change, so we can find a better method.
It is difficult to realize your idea in MongoDB. Your idea stems from the counter that provides identity in many relational databases.
In MongoDB, if you need to sort blog posts, you can use time or other “field” suitable for sorting.
Love Mongo！ Have Fun！
