Thanks
Where does the data come from?
Is it all loaded up from a file at start-up? Or is it built-up over time as the process(es) run? Other?
====>From database, do some transform. Once done, never change.

Could you post a few (2 or 3) examples of the keys + associated values? ====>Dont have it for now. value is mixed combination of hash/array/refs of hash,of array, of refs.
Is the entire dataset required for every iteration?
====>yes.
What do you do with the data when the program(s) end?
====>discards. after the program end , i will get a new data, and insert/update to database.
Do you save it some where? Discard it and re-build it next time the program runs? ====>mysql
Or is the data-structure built once as you process each log file, some statistics derived from it and then discarded never to be used again?
====>see above.
Thanks.~
