Hi Jannik,
Did you think to use a graph database?
No need to solve circular dependencies and probably more efficient for querying.
I did not try but there is an example here:
https://github.com/quentinplessis/smalltalk-neo4j
Cheers,
Christophe.
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 ?
Cheers
I’m confused by what you want to do but you can try ston.

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,
