Just to clarify, we might well do soon. In the current plan to
de-duplicate data between CKAN and DGU, DGU will make a request to CKAN
for each package view, rather than going to MySQL for it. David is
investigating it prior to a meeting we'll be having next Monday to
discuss the new architecture and I think a redis cache may be a very
important piece of the performance puzzle for that use case.

Cheers,

James
