Hello everybody, the current version of NDB stores Array/Hash/GeneralRubyObjects using the Marshal.dump/load methods. This is relatively fast but not portable. Ie it is difficult to use the database from an application coded in another language due to Marshal being Ruby specific. I could use yaml of course but I am wondering if this is fast enough. Any opinions on this? best regards, George Moschovitis -- www.navel.gr | tel: +30 2106898050 | fax: +30 2106898437 web appliction engine: http://www.navel.gr/nitro have fun: http://www.joy.gr
