增加弹性搜索 Kubernetes 中的分片数量

Question

部署了一个Elasticsearchon GKE. ECK有3个主节点和2个数据节点。创建包含 1 个分片和 1 个副本的索引时，当分片计数达到 1000 时，会收到 400 错误响应。

是否可以增加分片数量？请建议一种增加分片数量的方法。

Answer 1

您可以按如下方式更改分片编号。有关更多详细信息，请参阅集群更新设置 API 。我建议您在测试后应用它。

PUT /_cluster/settings
{
    "persistent" : {
        "cluster.max_shards_per_node" : 3000
    }
}
