Title
Body
I want to store different data to one collection in MongoDb and have Spring data beans with appropriate field.. Sorry, I've skipped details. Parent bean: class A int a Childs: class B extends A double b class C extends A String c So, there is following document in mongo {a : 1, b : 2.3, c : "Test"} When I fetch data, it is ok. But, when I call save method from CrudRepository for B, it rewrites all data and I lose C. I know only one good option to create custom save method with incremental updates, such as update.set("b", newvalue)... but with reflection. Do you have any other ideas? Thanks in advance.
