Digress:Recently, I have written several series of "VB omnipotent". The original intention of this series of articles is to subvert the prejudice of many programmers on the "non-Object-Oriented" language "VB! Of course, I have expected that this statement will inevitably lead to the "Siege" of people who do not know the truth. However, I still want to
to store the data, but the 122 Byte warehouse in the data kicked off.LRU removal mechanismmemcached Expiration data removal mechanism:When a value expires, it is not removed from memory, so stats statistics, Curr_items still have its information;When the value is taken, determine whether it expires, if expired, return empty, and empty, at this time curr_items is reduced;There have been no get before, will not automatically delete;Use an empty chunk only when a new value occupies its place.This
