This is not clear to me.
you can save a model in Ston or other
and you can query it in Moose.
What are the size of your models because you can load them all and query them.
to save it outside the image :)
But that you can do it in MSE, STON (with one line), Fuel,

But you can query a model with MooseQuery. Why do you need something else?

In fact, I need to save models and query them.
I think we can do it with Gemstone. But I thought we can have something similar with MongoDB.
In fact, the point is « how to identify circular references » to avoid infinite loop in Voyage ?

I’m confused by what you want to do but you can try ston.
Stef
The idea is to use it at runtime. So need to make queries.
But the idea of MSE serialization is good.
Now I don’t know how we can manage the serialization strategy of MSE with the one of Voyage…

Hi,
what is the goal?
if it is only a backup store (to later retreive the entire model), you
could try something similar to the MSE serialization (done with a
visitor).
So it would be a 1 level tree

Hi everyone,
I am trying to save a moose model into MongoDB, using Voyage (Pharo
7, Moose 8).
My problem is that it is not a tree. So I declared MooseEntity as
voyageRoot.
Now, it seems I have a loop into my graph.
Do you have any idea of ho to debug that ?
Cheers,
