For some time, I’ve been digging through Memcached related articles and blog posts over the web in order to understand how people are actually using it. Most of the articles are kinda equivalent. But the use of version in the cache seems more standard and improve form of managing the cache. When, cache keys are managed using version numbers, one does not have to worry about cache conflict issues also that may occur in certain update transactions because Memcached use LRU (Least Recently Used) to remove old cache values.

Here are some links I have gone through:
