问题场景
版本信息：ElasticSearch 7.13.3
系统版本：CentOS 7.0
需要将Mysql中数据批量导入到ElasticSearch中，从Gitee上找到一套开源源码下载地址，一顿操作后成功导入ElasticSearch

查询其他存在的索引visit_log，比较了一下区别
执行
GET /visit_log，visit_log内容如下：
{ "visit_log" : { "aliases" : { }, "mappings" : { "properties" : { . ...... } }, "settings" : { "index" : { "routing" : { "allocation" : { "include" : { "_tier_preference" : "data_content" } } }, "refresh_interval" : "1s", "number_of_shards" : "5", "provided_name" : "visit_log", "creation_date" : "1626223525799", "store" : { "type" : "fs" }, "number_of_replicas" : "1", "uuid" : "20dr00TpTtSsa4QEegFF8Q", "version" : { "created" : "7130399" } } } } }执行
GET /edu_resourcereservation，edu_resourcereservation内容如下，
{ "edu_resourcereservation" : { "aliases" : { }, "mappings" : { "properties" : { . ...... } }, "settings" : { "index" : { "routing" : { "allocation" : { "include" : { "_tier_preference" : "data_content" } } }, "refresh_interval" : "-1", "number_of_shards" : "5", "provided_name" : "edu_resourcereservation", "creation_date" : "1626223525799", "store" : { "type" : "fs" }, "number_of_replicas" : "0", "uuid" : "TC-JnoQBSBSIDymyXYNIu9Q", "version" : { "created" : "7130399" } } } } } -
区别就是一个叫
refresh_interval的值为-1，改成1s。 这个属性有啥用？ 刷新间隔,默认1s,近实时,文档从索引到可以被检索中间间隔就是这个值 https://blog.csdn.net/qq_28988969/article/details/103514918这个值为啥会是-1，因为从Gitee上clone下来的Java代码里面生成索引的时候给手动设死成-1啦。。。PUT /edu_resourcereservation/_settings { "settings" : { "refresh_interval" : "1s" } }
解决办法：修改索引edu_resourcereservation属性settings的子属性refresh_interval 值为 1s
PUT /edu_resourcereservation/_settings
{
"settings" : {
"refresh_interval" : "1s"
}
}
