Embodiment Construction

[0045] A distributed database (DDB, Distributed Database) refers to a database in which data is stored on various computers in a computer network, and these computers may be called data storage nodes.

[0046] In related technologies, based on the read-write separation technology, the main database node usually processes data update tasks, and the standby database node processes all query tasks, so as to improve the processing performance of the distributed database system. When the query task processed by the standby database node is a real-time query task, the query result may be inaccurate because the data in the standby database node is not synchronized with the data in the main database node.

[0047] In order to solve the above technical problems, an embodiment of the present invention provides a data processing method, which reads the field information of the set field from the preset first configuration information corresponding to the received operation instruction; T...

Abstract

The invention discloses a data processing method and device and a server, and the method comprises the steps: reading the field information of a set field from first configuration information, whereinthe first configuration information is preset configuration information corresponding to a received operation instruction, the field information of the set field is used for describing node equipmentfor processing a query task corresponding to the operation instruction and the node equipment comprises first node equipment serving as a main database or second node equipment serving as a standby database, determining node equipment for processing a query task corresponding to the operation instruction based on the field information, and when a query task corresponding to the operation instruction is detected, sending a query request to the determined node device.

Description

technical field [0001] The invention relates to the technical field of financial technology (Fintech) distributed databases, in particular to a data processing method, device and server. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field, and the traditional financial industry is gradually transforming into financial technology. However, due to the security and real-time requirements of the financial industry, financial technology also puts higher demands on technology. requirements. In the field of financial technology, distributed databases usually adopt a one-master and multiple-standby architecture, which includes a master database node and multiple standby database nodes. In related technologies, the main database node usually processes data update tasks, and the standby database node processes query tasks, which may lead to inaccurate query results.
