Re: [hibernate-dev] Storing values at the session level

Unfortunately there is no getter for the session owner on

Hi, I'm looking into ways for reducing the number of datastore roundtrips in OGM [1]. One idea is to fetch associations embedded within entity documents (e.g. in MongoDB) when loading such document. We'd "remember" the entity document and could later on retrieve the association from it without going to the store a second time. The problem is the "remembering" part. There is no session-scoped storage facility as of today which I could use. I contemplated making OgmSession deal with this, but I can't access that from persisters etc. Instead I'm seeing the wrapped SessionImpl (to which OgmSession delegates for many operations) and I couldn't find a way to reach the wrapping OgmSession instance. Now I noticed the concept of "SessionOwner" in SessionImpl and am wondering whether I could make use of this. When creating the SessionImpl, I could pass the OgmSession as owner and have it maintain a session-scoped storage. Unfortunately there is no getter for the session owner on SessionFactoryImplementor, though. Would it be feasible to add this getter and thus make a session's owner accessible? Or is there any other (better) way to achieve what I described? Many thanks, --Gunnar [1] https://hibernate.atlassian.net/browse/OGM-469
