http://data.xxxx.com:9200/_sql?sql=select * from t_base_student limit 10

SELECT identity_id,person_id,sum(resource_size_int) as sumall FROM t_resource_info group by identity_id,person_id order by sumall desc limit 

• Explain SQL to elasticsearch query DSL

http://localhost:9200/_sql/_explain?sql=select * from indexName limit 10
