I would like to read a large finitemap off of a disk faster than the time it takes to read the entire list of pairs. My solution is to save it as a bunch of smaller lists of pairs covering various key intervals (or recency intervals). I then can readfile all of these lists back into a bunch of finitemaps. Because readfile is lazy my program can start very quickly without waiting to read the contents of all of these files. To make this solution work, I need some datastructure that looks like a finitemap but operates on a bunch of them organized either in parallel (key interval model) or series (time interval model). Is there some pre-existing data structure that does this or do I need to roll my own? Or is there a better way to (de-)serialize FiniteMaps? -Alex- ______________________________________________________________ S. Alexander Jacobson tel:917-770-6565 http://alexjacobson.com
