Abstract

The present disclosure relates to a traffic adjustment method, device, device and storage medium for data synchronization, the method is applicable to a distributed database, the distributed database includes a main storage cluster and a backup storage cluster, and the main storage cluster is used for slave Obtaining data from the storage log of the distributed database, and synchronizing the data to the backup storage cluster for backup, the method includes: monitoring the scale ratio between the main storage cluster and the backup storage cluster; When the scale ratio changes, adjust the synchronization of the data from the main storage cluster to the The upper limit of traffic used by the backup storage cluster, so that the upper limit matches the changed scale ratio. The technical solution provided by the disclosure can realize automatic flow adjustment of data synchronization in a distributed database and reduce manual operations.

Description

technical field [0001] The present disclosure relates to the technical field of distributed storage, and in particular to a flow adjustment method, device, equipment and storage medium for data synchronization. Background technique [0002] Distributed databases often require multiple clusters to synchronize data. Usually, the primary cluster asynchronously reads data from the log and writes it to the standby cluster. However, usually the scales of the primary cluster and the standby cluster are inconsistent, or the service data is not exactly the same. Synchronizing to the standby cluster based on the traffic of the primary cluster may cause excessive pressure on the standby cluster. Current solutions usually limit synchronization. However, the level of current limiting needs to be customized manually, and the expansion or reduction of the scale of the backup cluster also requires manual adjustment of the current limiting of synchronization, which is inconvenient to opera...
