Technical Perspective: Scaling Dynamic Hash Tables on Real Persistent Memory

AbstractByte-addressable persistent memory was considered in the data management community as long ago as 1986. Thatte saw the advantages for programmability in unifying the abstractions of byte-addressable RAM with persistence [2]. Thatte's context was object-oriented databases containing a variety data structures that would be awkward to transform into the block-oriented abstractions provided by typical secondary storage. Thatte's proposed physical instantiation of persistent memory was a disk-backed device, although it is unclear whether such a device was ever built. Thatte recognized the importance of recovery to the overall scheme.
