Funnily enough I have been playing around with the MaxMind data this week.
I have a Lua + LPEG script which converts the MaxMind CSV files into a Lua
data structure. This script is rather meta because the CSV data parser is
created by a CSV header parser which is created by the lpeg re parser. Its
output is a lua module containing the data structure. This output module
is compiled with luac so that the whole thing can be loaded in a few
seconds. The compiled file is half a gigabyte and lua uses 1.75GB once it
is loaded. I have another script that uses this module to process
logs looking for users whose webmail accounts might have been compromised.
It takes about a minute to process 200MB of logs and uses 3GB RAM...
