Re: [UrbanSim-Users] using mysql for estimation input

Hana,

we created a cache directory but the problem is that the
"input_configuration" section is not used at all so
I think it should be removed somehow as it is confusing : it is not
possible to run the estimation *without* a
cache and only with a mysql database that would be flushed to cache
at runtime. Or did I miss the point of
having that "input_configuration" section in the my_estimation_config :)
