Er, yes. You can't really cache queries that write to the database, and it doesn't make sense to cache queries where the answers change for every query. A cache is only useful where the same query returns the same result (for a while, at least) and is executed very, very often. > Can you give the Real Example where memcached is used heavily. Google can. You'll need to build your independent research skills if you're going to succeed at what you're doing; it will not work well for you to rely on others making all the effort to explain everything to you. You will usually get better results when you ask people for help if you can show them that you have already made an effort to discover the answer for yourself. > fore.g How Facebook, You tube use it .
