Hi @landon30 - that's more of a fundamental MongoDriver ask than it is of the vertex client to that driver. I'd ask over at MongoDB.

you can see spring-data mongodb

• A field annotated with @id (org.springframework.data.annotation.Id) will be mapped to the '_id' field.
• A field without an annotation but named id will be mapped to the '_id' field.

i think some api usage an refer to spring-data mongodb

Hi @landon30
As I see, the mongo driver supports custom Id field.
You can put the custom generated id into the _id field of the inserted document.
You can also use another field as Id by creating an index to that field.
