A cache will be developed at some point.  You are welcome to help.  I
have some things I plan to contribute and a few people have posted
sample code for their ideas.

No, I don't think it ever does.  CDBI hits the database first before
checking the index.

Those people are not correct though.  That is why all of the methods
have those long ugly names referring to "object index" and not to
"cache."

There's a bit more to it.  You would need to avoid hitting the database
in places where it is currently hit, and you would also need to cache
the results of searches to really make this useful.  Nothing terrible
though.

There's really nothing big holding this back at the moment except people
who are familiar enough with CDBI finding time to work on it.
