Question

I have installed the latest embedded binaries from NuGet and am using this code to store a ‘product’ poco. After a bit, the process dies with an OutOfMemoryException. Is storing this much data out of scope for Raven?

Thank you.

var store = new EmbeddableDocumentStore { DataDirectory = @"C:\temp\ravendata", UseEmbeddedHttpServer = true };
store.Initialize();

using (var session = store.OpenSession())
{
    foreach (var item in Parsers.GetProducts().ToList())
    {
        session.Store(item);

    }
    session.SaveChanges();
    //var rdbList = session.Query<Product>().ToList();
}

How big of a batch are you doing? It looks like people have success with 256 batch sizes. Seems like much more causes timeouts and memory exceptions.

*EDIT: It sounds like it is also recommended to make a new session per batch so as to not keep the session open too long which can cause timeout errors.
