Abstract

The invention discloses a data source switching method and device, a computer device and a storage medium, and relates to the technical field of databases. The data source switching method comprises the steps of controlling an auxiliary data source to be in long connection with a main data source; predicting two time points with minimum transaction volume in a future transaction period, namely a first time point and a second time point; or predicting two time points with the minimum transaction failure rate in a future transaction period, namely a third time point and a fourth time point; whena first time point is reached, controlling to switch the main data source to an auxiliary data source, and when a second time point is reached, controlling to switch the auxiliary data source to themain data source; or, when a third time point is reached, controlling the main data source to be switched to the auxiliary data source, and when a fourth time point is reached, controlling the auxiliary data source to be switched to the main data source. According to the invention, high transaction performance can be maintained after switching, and transaction delay is reduced.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a data source switching method, device, computer equipment and storage medium. Background technique [0002] Databases are key infrastructures in the fields of finance, transportation, commerce, and even the entire society. Continuous availability is the guarantee for databases to continuously provide services to users. In the actual application of the database, due to considerations such as database data security, data processing efficiency, database operation and maintenance costs, and business development requirements, there may be a need for data source switching. For example, the database data source currently used by the business system needs to be Switch to a database data source with low operation and maintenance costs. [0003] Switching database data sources is a high-risk operation. If not handled properly, it can easily lead to business system paralysis. The tradi...
