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 ?

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

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…

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 would like to have a lazy loading. Not all the model. We are using Orion, which makes the model partial.
In fact, we don’t need it for now, but we want to have this perspective.

Check the book you are author :) STON is textual serialisation format.
What are the size of your models because you can load them all and query them.
I would like to have a lazy loading. Not all the model.
This is not stroing in mongo that will give you that. You will have to change the loading of model parts and Moose does not support it.
In addition if you have a graph how to you specify that an entity that is referenced should not be loaded (transitively)
We are using Orion, which makes the model partial.
I do not get this.
In fact, we don’t need it for now, but we want to have this perspective.

Yann Lesage at synectique tried to do external storage of moose models.
He spent a lot of time on it, did several experiments. MongoDB was not the solution he chose in the end (cyril told yesterday me what it was but I already forgot :-) )
It was still very slow when he left the company (prior to it going bankrupt) and speedup was involving analyses to try to reduce the number of request to the DB.
Bottom line is: do you have months of full time development to put in it?

And it did not work when you have a graph…. And it was cyril (the other delaunay that did it ).

~2011 we created a Fuel exporter/importer for Moose models, which was available for some versions (I think was removed later because of a bug with huge files that couldn't fix). If I remember well, all the effort was in customizations to avoid serializing generated/derivative objects that could be regenerated on materialization. But no problem with circular references in the object graph. Now I have no idea how different could it be with the new Moose.

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,

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

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

Hum, probably better than mongoDB.
I will try. Thank you -- ~~Jannik Laval~~ Enseignant-chercheur Responsable Pédagogique Licence Coordonnateur de Projet IUT Lumière, Université Lumière Lyon 2 laboratoire DISP +33 4 78 77 43 06 http://www.jannik-laval.eu http://www.phratch.com http://www.approchealpes.info
