Aerospike + Intel® persistent memory
summary
Aerospike moves the primary index into persistent DIMMs built on Intel 3D XPoint so the on-disk SSTs stay intact and the in-memory index survives power cycles, turning multi-hour rebuilds into near-instant reattaches. Access uses byte-addressable mmap-style access that bypasses kernel I/O, tested with Intel DCP 4800 and upcoming PM DIMMs on Cascade Lake, uses the PMDK libraries, keeps throughput near DRAM levels while lowering memory cost and increasing index capacity.
