Performance introspection of graph databases [PDF]
Proceedings of the 6th International Systems and Storage Conference on - SYSTOR '13, 2013 The explosion of graph data in social and biological networks, recommendation systems, provenance databases, etc. makes graph storage and processing of paramount importance. We present a performance introspection framework for graph databases, PIG, which provides both a toolset and methodology for understanding graph database performance.
