A read-write control method, device and server

Abstract

Embodiments of the present invention provide a read-write control method, device, and server. The method includes: monitoring a data request for a data warehouse; the data request includes: a read data request or a write data request; according to the occupancy status of the write lock node of the storage location requested by the data request, assign the write lock node to the data request; When the data request is a read data request and the data request is assigned to a read lock node with a storage location, change the occupied state of the write lock node to unoccupied and release the read data request; when the data request is a write data request and the read lock node is not occupied , the write data request is released. In this way, the read operation and the write operation can be coordinated to be performed in sequence, and the problem of data processing result error or even task failure caused by parallel read and write can be avoided.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a read-write control method, device and server. Background technique [0002] Data Warehouse (DW) is a mainstream technology for storing massive data. At present, the data warehouse is often used to store data, and the data stored in the data warehouse is used for data analysis and machine learning training. [0003] The inventor found in the process of implementing the present invention that the data operations involved in the data warehouse are mainly data queries, that is, mainly read operations, and few write operations are involved. However, when a write operation is involved and the data requested to be modified by the write operation is being used by other data processing processes, errors in related data processing results or even task failures often result. Contents of the invention [0004] The purpose of the embodiments of the present invention is to prov...
