Embodiment 1

[0025] figure 1 It is a flow chart of the memory data management method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of managing memory data in a real-time business system with a large number of users and high concurrency scenarios. The method can be executed by the device for managing memory data provided by the embodiment of the present invention. The device can be implemented by hardware and / or It can be implemented by means of software, which can generally be integrated into computer equipment. Such as figure 1 As shown, it specifically includes the following steps:

[0026] S11. Build an in-memory database. The in-memory database includes a hash table. Each node of the hash table is a doubly linked list, and each node of the doubly linked list is used to point to correspondingly stored memory data.

[0027] Among them, the memory database is a database that puts data in the memory and directly operates it. It can sto...

Abstract

The embodiment of the invention discloses a memory data management method and device, computer equipment and a storage medium. The method comprises the steps that a memory database is constructed, the memory database comprises a hash table, each node of the hash table is a double linked list, and each node of the double linked list is used for pointing to correspondingly stored memory data; and associated storage is performed on the memory data in the hard disk file so as to enable the memory data to be persistent. According to the technical scheme provided by the embodiment of the invention, through combined use of the hash table and the double linked list, millisecond-level high-speed and large-concurrency data requests are realized, the response speed of user requests in a real-time service system is enhanced, the user experience is improved, and meanwhile; through content synchronization with corresponding hard disk files, on the basis of meeting high-speed access to the memory, persistence of the data can be ensured, so that the data can be recovered in time when encountering an abnormal condition, and data loss is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data storage, and in particular, to a management method, device, computer equipment, and storage medium for memory data. Background technique [0002] At present, with the increasing demand for information and data processing and the increasing variety of businesses in different fields, memory-based data management is becoming more and more important. By using the computer memory as a data carrier, since no hard disk is used, the I / O time overhead for the hard disk is saved, so that the efficiency of data storage and query can be significantly improved. However, due to the volatility of the memory, when the system encounters abnormal failures such as restarting, the data in the memory will disappear and cannot be recovered, resulting in losses. Contents of the invention [0003] Embodiments of the present invention provide a memory data management method, device, computer equi...
