Detailed Description

template<typename Key, typename Value, typename UpdateTag = std::string>
class DataStorm::FilteredKeyReader< Key, Value, UpdateTag >

The filtered reader to read data elements whose key match a given filter.

A filtered reader retains the current value of every key it has received and not since seen removed, so that it can resolve later partial updates against it. This per-key state is independent of the reader's sampleCount and sampleLifetime history settings, and is released when the reader receives the key's remove sample. A reader matching an unbounded set of keys therefore accumulates one current value per key.
