A service scheduling method, apparatus, device and storage medium

Abstract

The embodiment of the invention discloses a business scheduling method, device, equipment and storage medium. The method receives a processing request of a business order; responds to the processing request, determines the candidate computer room that has processed the business order as the target computer room; dispatches the business order to the target computer room for business processing; according to the business The result of the processing updates the business data for the business order, wherein each of the candidate computer rooms stores the business data, thereby solving the problem of weak anti-risk ability due to a single write point, and also solving the problem of The problem of strong consistency in multiple places will be greatly reduced. On the premise of maintaining the consistency of business data, the technical effect of ensuring the anti-risk capability of business data and increasing the performance of business processing is realized.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a service scheduling method, device, equipment and storage medium. Background technique [0002] In the multi-active operation scenario of the system in different places, that is, all the business of the system is distributed in two or more computer rooms for business processing. Due to the instability and delay of the network, as well as the uncontrollability of user access, it is easy to cause data loss. The wrong sequence of read and write operations will cause data consistency problems and further affect the entire business logic. [0003] There are usually two solutions: one is to use a single write point to write the business data corresponding to the business into a computer room, which can maintain data consistency and access is more efficient, but the anti-risk ability is weak. When writing When the node is unavailable, the entire system...

[0002] In the multi-active operation scenario of the system in different places, that is, all the business of the system is distributed in two or more computer rooms for business processing. Due to the instability and delay of the network, as well as the uncontrollability of user access, it is easy to cause data loss. The sequence of read and write operations is wrong, which will cause data consistency problems and further affect the entire business logic

[0003] There are usually two solutions: one is to use a single write point to write the business data corresponding to the business into a computer room, which can maintain data consistency and access is more efficient, but the anti-risk ability is weak. When writing When the node is unavailable, the entire system will be unavailable; the second is to adopt the multi-regional strong consistency scheme. Among them, the multi-regional strong consistency scheme is a read-write separation mechanism across the computer room. All write operations are directed to a computer room. Operations can be performed in the secondary database of each computer room, or can be bound to the main computer room, which can maintain data consistency and have better anti-risk capabilities, but the performance will be greatly reduced and become a system bottleneck
