--------------------------------------

             Summary: Data Store
                 Key: ISPN-11081
                 URL: https://issues.redhat.com/browse/ISPN-11081
             Project: Infinispan
          Issue Type: Task
          Components: Core
    Affects Versions: 10.1.0.CR1
            Reporter: Tristan Tarrant
            Assignee: Dan Berindei
             Fix For: 11.0.0.Final


In scenarios where Infinispan is used as a persistent data store, the elasticity provided by rebalancing on scaling down (either voluntarily or because of node failure) can lead to data loss, even with persistent caches if all the owners of a segment leave the cluster before rebalancing can be completed. The remaining cluster should prevent writes to the lost segments until the nodes that own them are restarted.

It should be possible to configure Infinispan so that elasticity only applies when scaling up, i.e. adding a node will cause a rebalance.
