Description:
This program illustrates the concept of Datacache. In CacheData, intermediate nodes cache the data to serve future requests instead of fetching data from the data center.Node2 get the data from DataCenter and cache it on the hash table. When the intermediate node request the same data it will serve the request from its hashtable. Data cache retains popular data items for a long period of time and other data items are invalidated within a short period due to the limited cache space. Once the time period runs out data items are invalidated and removed from the data cache.Using the Socket programming Node and data center are connected and data transmitted between them using ObjectInputStream and ObjectOutputStream classes.
Cache the data in Intermediate nodes Using Java :
