Problems solved by technology

In order to achieve failover on the basis of avoiding the simultaneous operation of the master and backup, you can use the database direct connection method to write data in different places, or use the state control method to control the status of the master database and the standby database respectively, but these methods are either time-consuming. , or the operation is complicated, which reduces the efficiency of failover

Embodiment Construction

[0020] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0021] In the logical data center LDC, the data is divided according to the logic when storing. For example, assuming that 10,000 data are stored in the LDC, these data can be divided into 100 parts for storage, then each part can be called a "data shard" ". When dividing data, an exemplary way can be to divide according to the last two digits of the data ID. For example, the data with the last...

Abstract

The invention discloses a failover method and device. The method comprises the following steps: according to a data fragment with a failure, searching a service mapping relationship to obtain a master service unit storing the data fragment, and searching a backup mapping relationship to obtain a backup service unit for backup of the data fragment; and forwarding a data operation request for the data fragment in the master service unit to the backup service unit, so that the backup service unit carries out data operation on the data fragment. The failover method and device disclosed by the invention has the advantages that the failover complexity is reduced, and quick failover is achieved.

Description

technical field [0001] The present disclosure relates to network technologies, and in particular to a failover method and device. Background technique [0002] In Internet data centers that provide business support, due to data security and reliability requirements, separate storage methods are usually used when storing data. For example, a data center LDC (Logical Data Center) deployed in a logical manner can be Deploy data in different computer rooms. For example, some data is deployed in a computer room in Hangzhou as the main database, and another computer room in Shenzhen has a backup of the data as a backup database, so that when the Hangzhou computer room fails, the Shenzhen computer room can provide the same business services. This method is Failover , also known as failover, is a backup operation mechanism. [0003] In related technologies, when performing failover, it is also necessary to ensure that the main database and the standby database cannot be operated a...
