What is the purpose of the hash here? Do you need to build some lookup index? Sort or categorize?

Natural fit for a preprocessor is to function as a filter. Keep state but don't slurp the data. You can pipe it and stream it. But if complicated queries are required, then a database model might be more suitable.
