In MongoDB, the createdCollectionAutomatically field is an attribute that can be accessed through the db.getCollectionInfos() method. It indicates whether a collection was created automatically or not.
When you create a collection explicitly using the createCollection() method, the createdCollectionAutomatically field for that collection will be set to false. On the other hand, if a collection is created implicitly (e.g., by inserting documents into it), the field will be set to true.
Here’s an example of how you can check the value of this field for all collections in a database:
const collections = db.getCollectionInfos();
collections.forEach(collection => {
console.log(collection.name, "was created automatically:", collection.options.createdCollectionAutomatically);
});
This code will output whether each collection was created automatically or not.
