Open Distro for Elasticsearch SQL

Open Distro for Elasticsearch enables you to extract insights out of Elasticsearch using the familiar SQL query syntax. Use aggregations, group by, and where clauses to investigate your data. Read your data as JSON documents or CSV tables so you have the flexibility to use the format that works best for you.

SQL Related Projects

The following projects have been merged into this repository as separate folders as of July 9, 2020. Please refer to links below for details. This document will focus on the SQL plugin for Elasticsearch.

Documentation

Please refer to the SQL Language Reference Manual, Piped Processing Language (PPL) Reference Manual and Technical Documentation for detailed information on installing and configuring opendistro-elasticsearch-sql plugin. Looking to contribute? Read the instructions on Development Guide and then submit a patch!

SQL Engine V2

Recently we have been actively improving our query engine primarily for better correctness and extensibility. Behind the scene, the new enhanced engine has already supported the new released Piped Processing Language. However, it was experimental and disabled by default for SQL query processing. With most important features and full testing complete, now we're ready to promote it as our default SQL query engine. Please find more details in SQL Engine V2 - Release Notes.

Setup

Install as plugin: build plugin from source code by following the instruction in Build section and install it to your Elasticsearch.

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}.

Build

The package uses the Gradle build system.

Checkout this package from version control.
To build from command line set JAVA_HOME to point to a JDK >=14
Run ./gradlew build

Basic Usage

To use the feature, send requests to the _opendistro/_sql URI. You can use a request parameter or the request body (recommended).

Simple query

POST https://<host>:<port>/_opendistro/_sql
{
  "query": "SELECT * FROM my-index LIMIT 50"
}

Explain SQL to elasticsearch query DSL

POST _opendistro/_sql/_explain
{
  "query": "SELECT * FROM my-index LIMIT 50"
}

For a sample curl command with the Open Distro for Elasticsearch Security plugin, try:

curl -XPOST https://localhost:9200/_opendistro/_sql -u admin:admin -k -d '{"query": "SELECT * FROM my-index LIMIT 10"}' -H 'Content-Type: application/json'

SQL Usage

Query

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

Aggregation

  SELECT COUNT(*),SUM(age),MIN(age) as m, MAX(age),AVG(age)
  FROM bank
  GROUP BY gender
  HAVING m >= 20
  ORDER BY SUM(age), m DESC

Join

  SELECT b1.firstname, b1.lastname, b2.age
  FROM bank b1
  LEFT JOIN bank b2
  ON b1.age = b2.age AND b1.state = b2.state

Show

  SHOW TABLES LIKE ban%
  DESCRIBE TABLES LIKE bank

Delete

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

Beyond SQL

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

Nested Field

  SELECT address FROM bank b, b.nestedField e WHERE b.state = 'WA' and e.name = 'test'

  SELECT address, nested(nestedField.name)
  FROM bank
  WHERE nested(nestedField, nestedField.state = 'WA' AND nestedField.name = 'test')
     OR nested(nestedField.state) = 'CA'

Aggregations

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

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

Select type or pattern

  SELECT * FROM indexName/type
  SELECT * FROM index*
