             Summary: NVDIMM support for LLAP Cache
                 Key: HIVE-13029
                 URL: https://issues.apache.org/jira/browse/HIVE-13029
             Project: Hive
          Issue Type: New Feature
          Components: llap
    Affects Versions: 2.1.0
            Reporter: Gopal V
            Assignee: Gopal V


LLAP cache has been designed so that the cache can be offloaded easily to a pmem API without restart coherence.

The tricky part about NVDIMMs are restart coherence, while most of the cache gains can be obtained without keeping state across refreshes.
