Getting Koha to run persistently (and to do so safely!) seems like a higher
priority in my estimation than the conversion to DBIC, if for no other
reason than pervasive use of DBIC is going to seriously impede CGI
performance. In mean time, I find that applying small, judicious use of
local caching often gives a high return on very little time and additional
code while not interfering with the API.

You are correct that invalidation of caches is hard problem, but I<br>
assume that caching over DBIx::Class would take care of invalidation,<br>
but I might be wrong.</blockquote><div><br></div><div>DBIx::Class handles c=
