eff_i_g,
You really haven't said anything at all about how the program works or how it decides what data it needs and when.

Since many of your fields are not needed, they need not be included in your data structure provided you can no in advance that they won't be needed. If only 1 id is ever worked with at a time, then there is not a need to ever load more than one record in memory at a time. Alternatively, it may be possible to employ a MRU cache such that the splits are cached in arrays but only a fixed number are cached where the most recently used stay in cache and others expire.

Try to put yourself in my shoes. Read what you have written about your program, your datastructure, and your problem and see if you feel you have provided the necessary information to help. Again, we are just guessing.

Cheers - L~R
