Answer 1

std::map is fine given that size of key and value is small and the available memory is large ( for about 100million pairs). If its not the case, and you want to run a program over the key-value pairs, consider using a standard MapReduce API. Map Reduce is specifically meant to be used on distributed systems and process large data specially key-value pairs. Also there are nice C++ APIs for Map Reduce. http://en.wikipedia.org/wiki/MapReduce
