go-pmem is a project that adds native persistent memory support to Go. This is
achieved through a combination of language extensions, compiler instrumentation,
and runtime changes. Detailed design and implementation details of go-pmem
can be found in the ATC 2020 paper
on go-pmem. We have also created a website
which contains additional documentation and performance reports. go-pmem is
based on the 1.15 release version of Go.
The persistent memory changes introduced in go-pmem is currently supported
only on Linux amd64. To compile the codebase:
$ cd src
$ ./make.bash
The compiled Go binary will be placed in the bin/ directory. An example
application (example.go) written to use persistent memory features provided by
go-pmem can be found in the design/ folder. This application depends on the
go-pmem-transaction package and
can be compiled as follows:
$ GO111MODULE=off ../bin/go get -u github.com/vmware/go-pmem-transaction/...
$ cd design
$ GO111MODULE=off ../bin/go build -txn example.go
$ ./example
The official Go documentation on building the Go compiler can be found here.
go-pmem-transaction project provides two packages that go-pmem depends on.
The pmem package provides APIs to initialize persistent memory and access
persistent memory data through named objects. The transaction package provides
the transactional functionalities that go-pmem uses for enabling crash-consistent
persistent memory data updates.

Go Redis is a Go implementation of Redis designed to run on persistent memory. It is multi-threaded and implements a subset of the Redis commands. The advantages of Go Redis are: much faster database load time on a server restart due to its data being readily available in persistent memory and much higher data throughput thanks to the multithreaded Go implementation.
