elasticsearch8.5.2 报错(SearchPhaseExecutionException: all shards failed)

一、问题logstash突然无法对elasticsearch服务进行读写操作了,提示elasticsearch的地址有问题,检测elasticsearch发现端口存在。查看日志发现有报错。二、问题原因有一些索引的数据损坏了三、解决官网文档:https://www.elastic.co/guide/cn/elasticsearch/guide/cn/_cluster_health.html1、查看索引信息curl-XGET'http://localhost:9200/_cluster/health?pretty=true'{"cluster_name":"test","status":"yell

arrays - 去 : how to Assign all elements in 2 by 2 array of variable size?

我在使用GO使用文本文件中的矩阵填充二维数组时遇到问题。我遇到的主要问题是创建一个二维数组,因为我必须计算数组的维度,而GO似乎不接受数组维度中的VAR:nb_lines=numberoflineofthearraynb_col=numberofcolumnsofthearray//readmatrixfromfilewhole_file,_:=ioutil.ReadFile("test2.txt")//geteachlineofthefileintab_whole_filetab_whole_file:=strings.Split(string(whole_file),"\n")//

Golang regexp.ReplaceAllString 忽略替换字符串 "$X_"

我正在尝试使用我找到的正则表达式将CamelCase转换为snake_casehere.这是我正在使用的代码片段:in:="camelCase"varre1=regexp.MustCompile(`(.)([A-Z][a-z]+)`)out:=re1.ReplaceAllString(in,"$1_$2")正则表达式将匹配lCase。$1这里是l,$2是Case,所以使用替换字符串"$1_$2"应该导致camel_Case。相反,它会导致cameCase。将替换字符串更改为"$1_"会导致came。如果我将其更改为"$1+$2",结果将是camel+Case,如预期的那样(seepla
