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, ...

Abstract

The invention provides a technology for accelerating the performance of a traditional relational database through a nonvolatile storage system. The method aims at the requirements of a relational database system widely applied to various information system software related to cloud computing and the Internet of Things for performance improvement at present. A nonvolatile storage system is introduced, and by accelerating an intermediate cache system of the relational database (through nonvolatile storage), the overall performance of the database is improved under the condition that both the response speed and the data security are considered. The method comprises the following two innovations: 1, an NVRAM (Non-Volatile Random Access Memory) is applied on a database read-write cache; 2, theproblem of high availability of data is solved by maintaining a core data structure of the relational database through NVRAM resources; the invention has good applicability in the aspect of enhancingthe efficiency of cloud computing and Internet of Things edge computing systems.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a data management system for supporting cloud computing and edge computing, which uses non-volatile memory (NVRAM) technology to improve the I / O performance of a relational database system. Background technique [0002] In recent years, with the rapid development of cloud computing and edge computing technology and the continuous landing of related applications, intelligent data applications based on data analysis and processing have begun to increase rapidly. This type of application involves a large amount of data query and cache, management, indexing and query, which poses new challenges to the performance of relational database systems. Especially in the edge computing scenario, under the need to consider the balance of power consumption, performance and stability, simply using high-capacity memory and high-speed SSD hard disk cannot solve the above-mentioned...
