    • NVDIMM support for LLAP cache

    Description

      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, since LLAP is not the system of record, HDFS is.
