,but I need cache to retrieve the data from database and put it in cache.So the I compare the cache with incoming tuples.Based on that I can proceed to next.That cache should be refreshed based on given time .What cache should I implement,so that all bolts use that single cache. NOTE:If I implement cache in bolt level the bolts are executed in each machine.So that all bolts are maintain each cache.So that I need topology level so that all bolts uses single cache. If anyone know this tell me.
