Hi Guys For my problem I need to store 400-800 million 20 characters keys in a dictionary and do counting. This data structure takes about 60-100 Gb of RAM. I am wondering if there are slick ways to map the dictionary to a file on disk and not store it in memory but still access it as dictionary object. Speed is not the main concern in this problem and persistence is not needed as the counting will only be done once on the data. We want the script to run on smaller memory machines if possible.
I did think about databases for this but intuitively it looks like a overkill coz for each key you have to first check whether it is already present and increase the count by 1 and if not then insert the key into dbase. Just want to take your opinion on this. Thanks! -Abhi _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
