Data processing method and system and equipment

Abstract

The embodiment of the invention provides a data processing method and system and device. The method comprises the following steps: storing main and standby synchronization state information of a plurality of computing units; each computing unit comprises a main node and at least one standby node, and the main and standby synchronization state information comprises a playback log identifier of the standby node; the playback log identifier is determined after the standby node performs data playback by using a master node synchronization log belonging to the same computing unit; a target computing unit is determined from the plurality of computing units according to the log identifier and the main and standby synchronization state information carried in the data processing request. a read request is received, and the read request is sent to at least one standby node in the target computing unit, so that the at least one standby node responds to the read request to feed back corresponding target data. According to the technical scheme provided by the embodiment of the invention, based on the coordination node, the main node and the at least one standby node, a one-write multi-read data processing effect is realized, the strong consistency of data processing is ensured, and the data processing efficiency can be effectively improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to data processing methods, systems and equipment. Background technique [0002] With the development of cloud computing technology, the database scale is also increasing. In order to meet the requirements of big data and high-efficiency database application, a distributed database architecture is proposed based on the existing centralized database. [0003] In the existing distributed database, a coordination node has multiple storage nodes and computing units. In order to ensure data safety and reliability, backup data is usually established for each node. For example, in a computing unit, assign at least one standby node for data backup to each primary node. However, only when the data on the standby node is lost or the primary node fails, the standby node can recover the data. In normal operation, when the coordinating node receives a data read request or a data ...

AI Technical Summary

Problems solved by technology

In normal operation, when the coordinating node receives a data read request or a data write request, it is completed by the master node in the corresponding computing unit, and the standby node in the computing unit will not participate in the data reading and writing work. Therefore, the standby node Although the data synchronized from the master node is stored in , the data is idle most of the time

When the demand for data processing is relatively large, it is difficult to meet the data processing needs of the database by only performing corresponding data read and write operations through limited master nodes
