hi all, i have a very large dictionary object that is built from a text file that is about 800 MB -- it contains several million keys. ideally i would like to pickle this object so that i wouldnt have to parse this large file to compute the dictionary every time i run my program. however currently the pickled file is over 300 MB and takes a very long time to write to disk - even longer than recomputing the dictionary from scratch.
i would like to split the dictionary into smaller ones, containing only hundreds of thousands of keys, and then try to pickle them. is there a way to easily do this? i.e. is there an easy way to make a wrapper for this such that i can access this dictionary as just one object, but underneath it's split into several? so that i can write my_dict[k] and get a value, or set my_dict[m] to some value without knowing which sub dictionary it's in. if there aren't known ways to do this, i would greatly apprciate any advice/examples on how to write this data structure from scratch, reusing as much of the dict() class as possible. thanks. large_dict[a] -- http://mail.python.org/mailman/listinfo/python-list
