Abstract

Partial replication enables scalability provided it can be supported with genuine ordering protocols, i.e., protocols in which only the nodes involved in a transaction need to participate. The coordinator-based Skeen ordering algorithm is genuine and uses a linear number of messages, but its performance depends on the coordinator' s location. In this work we evaluate the benefits of informed coordinator selection in geo-distributed transactional systems. We present an experimental evaluation of these techniques to assess their advantages over uninformed alternatives.
