## What it is
An Elasticsearch plugin that lets users query Elasticsearch indices using familiar SQL syntax instead of the native query DSL. It is officially deprecated in favor of x-pack SQL and OpenDistro SQL.

## Use cases
- query elasticsearch with sql
- run sql select statements against es indices
- explain sql queries as elasticsearch dsl
- use sql joins and aggregations on elasticsearch
- give analysts sql access to search data

## When to choose
- you need sql access on legacy elasticsearch 1.x-9.x clusters without x-pack
- you want a free apache-licensed sql layer for older es versions

## When to avoid
- starting a new project - use x-pack-sql or OpenDistro SQL instead
- you need actively maintained software with support

## Facets
- artifact type: plugin
- maturity: maintenance
- function: search-engine, database, parser
- domain: databases, developer-tools
- platform: jvm, self-hosted
- tags: elasticsearch-plugin, sql-query, deprecated, search
