> 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.
