Elasticsearch插件：elasticsearch-sql安装和使用

news/2024/12/22 1:20:06/

使用此插件，您可以使用熟悉的SQL语法查询elasticsearch。您还可以在SQL中使用ES函数。

有两种方法可以使用此插件：

  1. 使用其余的api 
http://localhost:9200/_sql?sql=select * from indexName limit 10

2. 或者通过浏览器访问 http://localhost:9200/_plugin/sql

./bin/elasticsearch-plugin install https://github.com/NLPchina/elasticsearch-sql/releases/download/6.3.1.0/elasticsearch-sql-6.3.1.1.zip

After doing this, you need to restart the Elasticsearch server. Otherwise you may get errors like Invalid index name [sql], must not start with '']; ","status":400}.

执行此操作后，您需要重新启动Elasticsearch服务器。否则你可能会收到错误

Invalid index name [sql], must not start with '']; ","status":400}。

重新启动Elasticsearch服务器

#停止Elasticsearch进程
kill `ps -ef | grep Elasticsearch | grep -v grep | awk '{print $2}'`
#启动Elasticsearch进程
/elasticsearch-5.4.3/bin/elasticsearch -d

基本用法

在elasticsearch 1.x / 2.x上，可以直接访问elasticsearch-sql web前端页面：

http://localhost:9200/_plugin/sql/

在elasticsearch 5.x / 6.x上,需要先下载个网站插件 download and extract site.

具体下载地址是：

https://github.com/NLPchina/elasticsearch-sql/releases/download/5.4.1.0/es-sql-site-standalone.zip

启动插件:

cd site-server
npm install express --save
node node-server.js
  • 简单的查询
http://localhost:9200/_sql?sql=select * from indexName limit 10
  • 解释SQL
http://localhost:9200/_sql/_explain?sql=select * from indexName limit 10

SQL用法

  • 简单查询

      SELECT * FROM bank WHERE age >30 AND gender = 'm'

  • 聚合查询

      select COUNT(*),SUM(age),MIN(age) as m, MAX(age),AVG(age)FROM bank GROUP BY gender ORDER BY SUM(age), m DESC

  • 删除

      DELETE FROM bank WHERE age >30 AND gender = 'm'

超越SQL

  • Search

      SELECT address FROM bank WHERE address = matchQuery('880 Holmes Lane') ORDER BY _score DESC LIMIT 3

  • 聚合

    • range age group 20-25,25-30,30-35,35-40

        SELECT COUNT(age) FROM bank GROUP BY range(age, 20,25,30,35,40)

    • range date group by day

        SELECT online FROM online GROUP BY date_histogram(field='insert_time','interval'='1d')

    • range date group by your config

        SELECT online FROM online GROUP BY date_range(field='insert_time','format'='yyyy-MM-dd' ,'2014-08-18','2014-08-17','now-8d','now-7d','now-6d','now')

  • ES Geographic（地理位置）

      SELECT * FROM locations WHERE GEO_BOUNDING_BOX(fieldname,100.0,1.0,101,0.0)

  • Select type

      SELECT * FROM indexName/type

SQL功能

  • SQL Select
  • SQL Delete
  • SQL Where
  • SQL Order By
  • SQL Group By
  • SQL AND & OR
  • SQL Like
  • SQL COUNT distinct
  • SQL In
  • SQL Between
  • SQL Aliases
  • SQL Not Null
  • SQL(ES) Date
  • SQL avg()
  • SQL count()
  • SQL last()
  • SQL max()
  • SQL min()
  • SQL sum()
  • SQL Nulls
  • SQL isnull()
  • SQL now()
  • SQL floor
  • SQL split
  • SQL trim
  • SQL log
  • SQL log10
  • SQL substring
  • SQL round
  • SQL sqrt
  • SQL concat_ws
  • SQL union and minus

支持JDBC (处于试验阶段的功能)

Check details : JDBC Support

public void testJDBC() throws Exception {Properties properties = new Properties();properties.put("url", "jdbc:elasticsearch://127.0.0.1:9300/" + TestsConstants.TEST_INDEX);DruidDataSource dds = (DruidDataSource) ElasticSearchDruidDataSourceFactory.createDataSource(properties);Connection connection = dds.getConnection();PreparedStatement ps = connection.prepareStatement("SELECT  gender,lastname,age from  " + TestsConstants.TEST_INDEX + " where lastname='Heath'");ResultSet resultSet = ps.executeQuery();List<String> result = new ArrayList<String>();while (resultSet.next()) {System.out.println(resultSet.getString("lastname") + "," + resultSet.getInt("age") + "," + resultSet.getString("gender"))}ps.close();connection.close();dds.close();}

 

Beyond sql features

  • ES TopHits
  • ES MISSING
  • ES STATS
  • ES GEO_INTERSECTS
  • ES GEO_BOUNDING_BOX
  • ES GEO_DISTANCE
  • ES GEOHASH_GRID aggregation
