Writing an object graph into a no-sql database [WAS] Re: [Seaside] ESUG SummerTalk - Fuel, binary object serializer

Sorry to come back with this old post, but now I am interested ;) Right now, I have a requirement where I need to write a graph into a file. I am using Fuel for that. Each graph, has its own file. In the image side I just store the filename, When I need to load it it reads such file and materialize it with Fuel. I was thinking going a step forward and use a key/value (a.k.a no-sql) database. With Fuel, I can take a graph, and serialize directly into a ByteArray, hence I can take a graph to swap, I assign an ID, and and save it into the database. In the image side, I keep that ID. Then, when needed, I search it in the database and then after with that ByteArray found, I materialize it with Fuel. So...first question is, do you think that could be faster/better than directly writing into a file as I am doing now? Now, which are the available Pharo wrappers for no-sql databases that let me do that? I would appreciate any link or documentation about them. What do I need to use such databases from Pharo? FFI and a library installed in my machine? are there binaries for Mac OS? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

Hi, The registration server does right now not provide a list... making it completely public would not be a good idea, but we can think of adding that to the registration system in the next development iteration.

Hi Would you like to be awake and ready to focus on the outstanding talks ESUG has to offer? Would you like to burn off some calories form all the socializing of the previous evening? Then why not go for a run in the morning in the amazing scenery that Edinburgh has to offer? So if you're interested bring your running gear with you. Yes, the idea is stolen from Java conferences [1] [2]. [1] http://wiki.eclipse.org/EclipseCon_Exercise_2011 [2] http://wiki.eclipse.org/ESE_Exercise_2010 Cheers Philippe
