Global Object Identification

[lambrosx77]

Is there a privileged way to resolve graphql best practices Global Object Identification with dgs?
https://graphql.org/learn/global-object-identification/

I'm using Postgresql with serials for my identifiers, I don't want uuid at this level. I'm loading datas using hibernate and repositories, everything work fine except that relay need global unique identifier.

I tried to customize Jackson with success for REST but without for dgs + graphql:

    @JsonGetter("id")
    public String idToGuid() {
        return Base64.getEncoder().encodeToString(new String("Activite_" + id).getBytes());
    }
    @JsonSetter("id")
    public void guidToId(String guid) {
        setId(Integer.parseInt(new String(Base64.getDecoder().decode(guid)).split("_")[1]));
    }

Or should I change my ids in the datafetchers using streams before sending it to relay? Or making a second field "guid" in my entities and using it in my schema? Should I use DTO? Or another way?

Same question to implement Node interface.

Could DGS implement those patterns?

Thank you for the advices.
