[infinispan-issues] [JBoss JIRA] (ISPN-6883) Remote Cache Store does does't work properly in compatibility mode

Remote Cache Store does does't work properly in compatibility mode ------------------------------------------------------------------ Key: ISPN-6883 URL: https://issues.jboss.org/browse/ISPN-6883 Project: Infinispan Issue Type: Bug Components: Loaders and Stores Affects Versions: 9.0.0.Alpha3 Reporter: Sebastian Łaskawiec Assignee: Tristan Tarrant Currently we can't use Remote Cache Store for Caches populated using REST with compatibility mode. The configuration for source cache looks like the following: {code} <distributed-cache name="default" mode="SYNC" segments="20" owners="2" remote-timeout="30000" start="EAGER"> <locking acquire-timeout="30000" concurrency-level="1000" striping="false"/> <transaction mode="NONE"/> <compatibility enabled="true" /> </distributed-cache> {code} Destination cache: {code} <distributed-cache name="default" mode="SYNC" segments="20" owners="2" remote-timeout="30000" start="EAGER"> <locking acquire-timeout="30000" concurrency-level="1000" striping="false"/> <transaction mode="NONE"/> <compatibility enabled="true" /> <remote-store cache="default" hotrod-wrapping="true" read-only="true"> <remote-server outbound-socket-binding="remote-store-hotrod-server" /> </remote-store> </distributed-cache> {code} With the configuration above, when performing [Rolling Upgrade|http://infinispan.org/docs/stable/user_guide/user_guide.html#steps_2] procedure I get: {code} 03:38:43,025
