Elasticsearch SQL是一个X-Pack组件,它允许针对Elasticsearch实时执行类似SQL的查询。无论使用REST接口,命令行还是JDBC,任何客户端都可以使用SQL对Elasticsearch中的数据进行原生搜索和聚合数据。可以将Elasticsearch SQL看作是一种翻译器,它可以将SQL翻译成Query DSL。
在Elasticsearch集群 6.5.4及之后版本中提供Open Distro for Elasticsearch SQL插件允许您使用SQL而不是Elasticsearch查询域特定语言(DSL)编写查询。熟悉SQL语言的用户,可以使用SQL语言在Elasticsearch中搜索数据。在Kibana中使用SQL语言搜索数据(推荐)在
