Embodiment Construction

[0059] First, the application scenarios and some vocabulary involved in the embodiments of the present application are introduced.

[0060] The method, device, device, and storage medium for expanding the capacity of a distributed database involved in the embodiments of the present application can be applied to the application scenario of expanding the capacity of a distributed database, and realize that the original storage nodes can be reused. Part of the data in the storage node is migrated to at least one expanded storage node, thereby improving resource utilization and improving capacity expansion efficiency.

[0061] The execution subject of the distributed database expansion method provided in the embodiment of the present application may be a distributed database expansion device or a distributed database expansion device (for the convenience of description, in this embodiment, the execution subject is the distributed database expansion device as example to illustrate)...

Abstract

Embodiments of the present application provide a capacity expansion method, device, apparatus, and storage medium of a distributed database. The method includes: obtaining a capacity expansion configuration instruction including capacity expansion indication information, wherein, the capacity expansion indication information is used to indicate information of at least one capacity expansion storage node; further, according to the expansion indication information and the current routing information of the distributed database, migration data corresponding to each original storage node in the distributed database is determined, and migration data in each original storage node is migrated to the at least one expansion storage node respectively. As can be seen, in the embodiment of the presentapplication, the original storage node can be multiplexed, and only part of the data in each of the original storage nodes needs to be migrated to the at least one expansion storage node, so that theresource utilization rate can be improved and the expansion efficiency can also be improved.

Description

technical field [0001] The present application relates to the technical field of data storage, and in particular to a method, device, equipment and storage medium for expanding the capacity of a distributed database. Background technique [0002] With the rise of the cloud era and the mobile Internet, a huge amount of network behavior data has been generated. Traditional single-node databases have been difficult to meet the storage of massive data, and distributed databases have emerged as the times require. [0003] In order to meet the high burst of massive data storage, the scalability of the distributed database is particularly important. In related technologies, by creating a new distributed database, and importing the data in the original distributed database into the new distributed database according to the new routing strategy, data expansion is completed; wherein, the number of storage nodes in the new distributed database is greater than The number of storage no...
