Storm data structures - map vs separated values? -


i'm using storm parse , save data kafka. data comes in identifiers , map<string,string> of varying size. after munging end goal cassandra.

should send data 1 block of tuples or split map , send each piece separately?

a tuple should represent "unit of work" next bolt in stream. if think of map single entity gets processed single, albeit complex, object map should emitted single tuple. if want different bolts independently processing different map attributes, break map subsequently processable subsets of attributes , emit multiple tuples.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
