[jboss-jira] [JBoss JIRA] (WFLY-738) Add clear cache operation on cache container and cache (accessible via admin console)

[Paul Ferraro (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-738?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Paul Ferraro closed WFLY-738.
-----------------------------
    Resolution: Won't Do


I'm rejecting this for a couple reasons:
# Such an operation is only generally safe for an invalidation cache.
# Such an operation would need RBAC.
# Clear is not an atomic operation in Infinispan, so this is an unsafe operation to begin with.
# The primary invalidation cache use case in WildFly is Hibernate's RegionFactory, which already has a clear operation.

> Add operation on infinispan subsystem to clear cache at cache container level (ie. clear all caches for the container) and at cache level.
> The implementation of the clear operation just calls the method #clear() on the org.infinispan.Cache interface. If needed we can clear the associated CacheStore (make it optional ?) and handle more complex cases.
