https://www.elastic.co/guide/en/elasticsearch/reference/8.8/cluster-allocation-explain.html#cluster-allocation-explain
我理解意思是说: Cluster allocation explain API 是 Elasticsearch 8 中的一个 API,用于提供关于特定分片当前分配情况的解释。使用此 API 可以查看某个集群中特定分片当前所在的节点、分片状态以及分片信息等相关信息。这对于集群管理员来说非常有用,因为他们可以使用此 API 来诊断集群中可能出现的问题,并实时了解集群的健康状况。
