Design and Evalution of an Edge-based Concurrency Protocol for Distributed Graph Databases


A new concurrency control protocol for distributed graph databases is described. It avoids the introduction of certain types of inconsistencies by aborting vulnerable transactions. An approximate model that allows computation of performance measures, including the fraction of aborted transactions, is developed. The accuracy of the approximations is assessed by comparing them with simulations, for a variety of parameter settings.
