Hi Martijn, You very well know that I am scouting for an in memory data base. I wish to use one in a future project. My question now is when do you think Ditto will be completed? Are you looking for other team members/developers? Also, in terms of features, how does it compare to other libraries such as the recently proposed Relational Tables by Dmitriy Arapov and Arkadiy Vertleyb?
