checkpoint only (shadow page technique version fixed)

[JonghyeokPark]

Logging & Recovery Prototype

• Use NVDIMM redo log buffer
• Capture the redo/undo logs for NVDIMM caching pages
• Exploit the shadowing page technique for consistency

DWB

• Use innodb_use_nvdimm_dwb option in your my.cnf
• Eliminate DWB writes to disks for both normal and NC pages

TODOs

• Remedy checkpoint and flush logic
