It is a system design problem . Suppose a http request is sent to server . Now Server maintains cache for fast retrieval . if link is present int the cache then it just takes a data from cache and return it to user but if not , then user will fetch that http address and then store it in its cache and return same to the user .
Problem is that there are many server and many global cache as expected in distributed system. Now when request is received by a server then how can we maintain global cache such that server can know which cache to query instead of querying each global cache as it will be inefficient. one approach can be...... maintain 26 global cache . Now when request is received by server it check the web link say , www.*a*bc.com ... here server will query cache-1 . Similarly cache-2 will take care of links with starts from "b"...www.*b*bc.com ....and so on.... above method will avoid duplicity in caches but will not be very efficient as a cache may have higher query rate than others... any other approach ?? -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
