Basically, it's the mapping of collection of embeddables with another collection of embeddables.
The problem is that this mapping is not supported by JPA or Hibernate, we need to find an alternative. Maybe a user could use entities instead of embeddables with some additional OGM specific annotation or properties.
Is there a way to define JSON as a supported entity, such that an user-provided converter can translate the data to a JSON structure and that gets stored directly in the DB?
Ideally, we should support this for document stores in general.
Sometimes users need to map this kind of document:
{ _id: ObjectId("abc"), userId: "123" experiments: { "experiment1" : {"variantA" : "variantValue1", "variantB", "VariantValue2" "variantC", "VariantValue3"}, "experiment2" : {"variantD", "VariantValue4"} } }Basically, it's the mapping of collection of embeddables with another collection of embeddables.
