Mongo CQRS support

[o-shevchenko]

Is it possible to use different entities for reading and write with Micronaut Data Mongo CrudRepository?

Use case: Let's say we have two entities Parent and Child.

data class Parent(
    @field:Id
    @GeneratedValue
    var id: Id = "",
    val name: String
)

data class Child(
    @field:Id
    @GeneratedValue
    var id: Id = "",
    val name: String
    val parentId: Id
)

We want to be able to save Child using Child entity specified above, but read entity to ChildQuery to read data from Mongo by a single call from two entities.

data class Child(
    @field:Id
    @GeneratedValue
    var id: Id = "",
    val name: String
    @Relation(value = Relation.Kind.MANY_TO_ONE)
    val parent: Parent
)

or

data class Child(
    @field:Id
    @GeneratedValue
    var id: Id = "",
    val name: String
    val parentName: String
)

How it can be done using a single repository?

@MongoRepository
interface ChildRepository : CrudRepository<Child, Id>

It should be possible to define multiple entities that are referencing the same collection. Sorry for the late reply.

Any example of that?
I was able to create two repositories, one for read and another for write.

That's what I meant, two different entities and repositories
