[ANNOUNCEMENT] es-sql 2.0.0 Query Elasticsearch using SQL

(Taowen) #1

We love SQL and want to leverage the full power of elasticsearch. Using syntax like

$ cat << EOF | es-sql
    WITH all_symbols AS (SELECT MAX(market_cap) AS max_all_times FROM symbol);
    WITH year_2000 AS (SELECT MAX(market_cap) AS max_at_2000 FROM all_symbols 
        WHERE ipo_year=2000)

You can create drill-down aggregation without deeply nested json

It is written in Python, it can be:

  • a python library to query elasticsearch ( https://pypi.python.org/pypi/es-sql )
  • a console command
  • a http server providing SQL api
  • we also use it to monitor Elasticsearch cluster itself, even querying metric from Elasticsearch to monitor business

If you like Java, there is also a Java version coming.

Compared to 1.x version, the WITH statement is changed to abide SQL syntax convention ( from WITH xxx AS yyy to WITH yyy AS (xxx) )
