             Summary: Always purge non-shared stores on cache startup
                 Key: ISPN-12210
                 URL: https://issues.redhat.com/browse/ISPN-12210
             Project: Infinispan
          Issue Type: Bug
          Components: Core, Loaders and Stores
    Affects Versions: 11.0.3.Final
            Reporter: Dan Berindei
             Fix For: 12.0.0.Final


{{purgeOnStartup}} is unsafe with shared stores, but it must be enabled for non-shared (private) stores in order to avoid resurrecting removed entries.

We can enhance the graceful cluster/cache shutdown operations to save a "disable purge" flag in the persisted state, and purge on cache startup the non-shared stores of any cache missing the "disable purge" flag. This will remove the need to ever disable {{purgeOnStartup}}.

Then we can ignore the {{purgeOnStartup}} setting and only log a warning that it will be ignored if the user enabled it for shared stores or disabled it for non-shared stores.
