Embodiment Construction
[0037] The present invention is realized by two parts of hardware and software, and the hardware part is realized by NVRAM equipment, and the current Optane NVRAM system of Intel Corporation can be adopted. The system connects with the x86 server through the PCIe interface, and its hardware device drivers support mainstream Linux and Windows systems. Therefore, it can be easily realized on the current mainstream data platform.
[0038]The software system is based on the mainstream InnoDB storage engine, which is the core storage engine of various widely used relational databases including MySQL DB and Maria DB. Provide memory data management driver for InnoDB data storage engine (NVRAM driver, see attached figure 1 ) to replace its original memory data management module (see attached figure 2 ). By introducing the management and operation capabilities of NVRAM as a data buffer layer, the data structure cache of the docking memory is replaced by the file system with NVRAM, ...
