In-place Rolling Upgrade Marshaller Changes ------------------------------------------- Key: ISPN-9620 URL: https://issues.jboss.org/browse/ISPN-9620 Project: Infinispan Issue Type: Enhancement Components: Core, Loaders and Stores Affects Versions: 9.4.0.Final Reporter: Ryan Emerson Assignee: Ryan Emerson Priority: Major Fix For: 10.1.0.Final In order to allow for compatibility between infinispan versions it is necessary for us to utilise a marshalling implementation at both the cluster (internal node-to-node communication) and persistence layer that is strictly defined but allows for future changes. This is necessary in order to facilitate both rolling and start/stop upgrades. Protocol buffers should be utilised as the wire/storage format, with protostream providing the implementation.
