That sounds interesting. Seems a similar approach but storing in memory. My Database having about 4GB should lead to a manageable size of Data for this method. Besides the difference that the information is stored in an even faster way than in a JSON or hashref in a DB the approach seems kind of similar from my point of view. I still do not get the real disadvantage of storing a cached element in a table. Nevertheless Cache::Memcached looks very nice, thank you for that.
