serialization - How to store HashMap values separately in scala? -

i have scala hashmap generated 1 app , used another. hashmap big,like 100mb of size or more.

var actmap = new collection.mutable.hashmap[string, seq[object]];

currently whole map loaded in memory sec app when starts.i trying load keys in memory , later when looking key in map,it should give value stored in disk. there anyway accomplish this? individually saving every value , accessing them on fly take lot of time if standard serialization used. alternatives?

you might want think using memory mapped files this. roll own.

assuming can alter interface , utilize 3rd party libraries at
