Data sharding adjustment method and device, equipment and readable storage medium

Abstract

The present disclosure relates to a data shard adjustment method, device, equipment and readable storage medium. The method comprises the following steps: monitoring a distributed cluster to obtain monitoring data of the distributed cluster; judging whether the distributed cluster currently satisfies a preset shard adjustment condition based on the monitoring data; and adjusting the distribution of the data shard on each node of the distributed cluster if the distributed cluster currently satisfies the preset shard adjustment condition. Since the judgment is based on the monitoring data, when it is judged that the distributed cluster currently satisfies the preset shard adjustment condition, the distribution of the data shard on each node of the distributed cluster is adjusted, which can avoid resource skewing, give full play to the advantages of the distributed cluster, and thus improve the retrieval performance and the stability of the system. Furthermore, manual intervention and manual operation can be reduced, automatic management can be realized, and the management cost and workload can be reduced.
