Abstract

The embodiment of the present invention relates to a sub-table deployment method, device and system in a Key / Value storage system. By obtaining the preset specified range to which the Key value range of the sub-table to be deployed belongs, and deploying the above-mentioned sub-table to be deployed in On a node device in the Key / Value storage system, the deployment of the sub-tables within the specified range deployed on at least two node devices can be balanced, and it can avoid that the sub-tables in a specified range are all concentrated in one or There are no subtables in the specified range on other node devices caused by several node devices, so that the node devices are fully utilized and the utilization rate of the node devices in the Key / Value storage system is improved.

Description

technical field [0001] Embodiments of the present invention relate to information storage technologies, and in particular, to a sub-table deployment method, device, and system in a Key / Value (Key / Value) storage system. Background technique [0002] The distributed key / value (Key / Value) storage system can be composed of a sub-table or multiple sub-tables deployed on at least two node devices, and each sub-table has a start Key value (StartKey) and an end Key value (EndKey ). When a subtable deployed on a node device increases to a certain extent, it will be automatically split into two subtables. [0003] However, in the process of sub-table creation (i.e. splitting) or sub-table movement, if sub-tables within a specified range (for example: time range, geographical range, etc.) are concentrated on one or several node devices, making There are no sub-tables within the specified range on other node devices, resulting in underutilization of the node devices, thereby reducing...
