Plugin cache issue

Hi,

We’re using plugin for displaying Popular Posts on our site, and we discovered strange thing. After deleting cache for views, every counter starts from zero. We had to clear cache, because data for today/week views was a little illogical (we had 6000 views / day in widget, and 5000 / week in widget for same post).

Is it possible to hold all data in database and cache table use only to remain data for specific time to incerase site performance ? It’ll be better to solve problems like this, when we need to clear cache, but we need to remain earlier data in database.

Thanks a lot
