Connectivity is a property of a graph as a whole, there is no way to
analyze it having just a part of all nodes and edges. Use of original
tables in language database or use of MyISAM tables makes the analysis
far too slow. Good thing with memory tables is not only in being
located in memory (which is not always true of course), the engine is
optimized for speed itself and the format is designed to allow that.
