Rolling upgrade source migrators should use the distributed iterator to collect keys ------------------------------------------------------------------------------------ Key: ISPN-4895 URL: https://issues.jboss.org/browse/ISPN-4895 Project: Infinispan Issue Type: Feature Request Components: Remote Protocols Affects Versions: 7.0.0.CR2 Reporter: Tristan Tarrant Assignee: William Burns Fix For: 7.1.0.Alpha1 currently the rolling upgrade migrators iterate all entries in the cache using org.infinispan.tasks.GlobalKeySetTask<K, V> and invoking cache.keySet().
