             Summary: Relax Cache.clear() semantics
                 Key: ISPN-3656
                 URL: https://issues.jboss.org/browse/ISPN-3656
             Project: Infinispan
          Issue Type: Enhancement
          Components: Core API, Loaders and Stores
            Reporter: Galder Zamarreño
            Assignee: Galder Zamarreño
             Fix For: 7.0.0.Final


Clear should be non-transactional, independent of the cache configuration. This is because a transactional clear would, if implemented strictly, required all cache keys to be locked, which could lead to global deadlocks, particularly in distributed caches.

Also, making cache clear cache contents eventually, not immediately would simplify AsyncStore implementation by relaxing the point at which clear happens. As an extension of this, it would simplify development of coalescing logic in other parts of Infinispan
