How to not persist a property without excluding it from Ktor serialization?

[a-vezzoli-02]

Is there a way, like an annotation, that prevents a property from being written in the database without also preventing it from being serialized as a Ktor JSON response?

data class Bank(
    @BsonId @JsonProperty("_id") val id: Id<Bank> = newId(),
    var name: String,
    var initialAmount: Double = 0.0,
    @JsonIgnore var currentAmount: Double?
)

In the example above, by adding @JsonIgnore, I'm disabling the currentAmount property serialization for the whole project, not only for KMongo.

I also know that I could disable null values from being persisted, but that's not something that I'm willing to do. I'm wondering if there is a way to exclude a property, regardless of the state, from the "mongo schema" without changing the whole serialization.

In this case, I'm using Jackson as the serialization provider.

You can provide custom Jackson modules for KMongo using https://litote.org/kmongo/dokka/kmongo/org.litote.kmongo.util/-k-mongo-configuration/register-bson-module.html
