Support for Total Order Multicast Transactions ---------------------------------------------- Key: ISPN-2635 URL: https://issues.jboss.org/browse/ISPN-2635 Project: Infinispan Issue Type: Feature Request Components: Transactions Reporter: Mircea Markus Assignee: Pedro Ruivo Priority: Blocker Fix For: 5.3.0.Alpha1, 5.3.0.Final Based on CloudTM's implementation. The Total Order based commit protocol is a multi-master scheme as currently Two Phase Commit implementation. This protocol relies on the concept of totally ordered delivery of messages which, informally, implies that each node which delivers a set of messages M, delivers them in the same order. This protocol comes with two advantages. 1) transactions can be committed in one phase, as they are delivered in the same order by the nodes that receive them. 2) it totally avoids deadlocks. The weakness point of this protocol is the fact that its implementation relies on a single thread per node which validates and commit transactions.
