go-pmem: Native Support for Programming Persistent Memory in Go
summary
go-pmem is an open-source extension to the Go 1.11 compiler and runtime that adds a garbage-collected persistent heap, native pointers with pointer swizzling on restart, and a new txn block implementing undo-logging for crash-consistent updates. It exposes pnew/pmake allocation, named objects, and GC-aware heap recovery. A feature‑poor Redis called go-redis-pmem is built with it and shows >5x throughput vs Redis on NVMe SSD, up to 20x faster restart, allocator up to 40x faster, and transactions several‑times faster than PMDK/Mnemosyne.
