mysql-pmem

Author: Trong-Dat Nguyen

This work modify mysql-5.7.20 to test pmem

install

Dependencies

• ndctl (for building PMDK and NVDIMM management)

• PMDK (for libpmem* libraries)

• libaio (for Native Linux AIO)

• You should install dependencies before building mysql from source code

Notice:

• We recommend you build the original MySQL first before building PB-NVM
• If you could not install libndctl and libdaxctl (v60.1 or later) during install PMDK, you also skip those libraries by using $ export NDCTL_ENABLE=n

Configuration
