[infinispan-issues] [JBoss JIRA] (ISPN-9111) Internal caches should be replicated across sites

Internal caches should be replicated across sites ------------------------------------------------- Key: ISPN-9111 URL: https://issues.jboss.org/browse/ISPN-9111 Project: Infinispan Issue Type: Enhancement Components: Cross-Site Replication, Remote Querying Reporter: Galder Zamarreño Assignee: Galder Zamarreño Labels: redhat-summit-18 Given a cache manager, we should look for all enabled x-site locations and add those sites as SYNC backups for the protobuf metadata cache. Without this data, the user has to implement its own code to make sure the data is added in each site which is troublesome. Using SYNC/FAIL combo turns out to be very buggy. In the initial test created, only one site was up and the other was not. The put call to replicate the metadata was failing (as a result of ISPN-9113) but this was going under the radar (more tests needed!), and it ended up waiting for the replication timeout to happen. Even after replication timeout happened, the put call was completing fine. This is because invocation batching was enabled for protobuf metadata cache which means any update failures would not make the cache operations fail.
