Querying Pinot

Ways to query Pinot

REST API on the Broker

Pinot can be queried via a broker endpoint as follows. This example assumes broker is running on localhost:8099

Standard-SQL endpoint

The Pinot REST API can be accessed by invoking POST operation with a JSON body containing the parameter sql to the /query/sql endpoint on a broker.

$ curl -H "Content-Type: application/json" -X POST \
   -d '{"sql":"select foo, count(*) from myTable group by foo limit 100"}' \
   http://localhost:8099/query/sql

PQL endpoint

Note

This endpoint is deprecated, and will soon be removed. The standard-SQL endpoint is the recommended endpoint.

The PQL endpoint can be accessed by invoking POST operation with a JSON body containing the parameter pql to the /query endpoint on a broker.

$ curl -H "Content-Type: application/json" -X POST \
   -d '{"pql":"select count(*) from myTable group by foo top 100"}' \
   http://localhost:8099/query

Query Console

Query Console can be used for running ad-hoc queries (checkbox available to query the PQL endpoint). The Query Console can be accessed by entering the <controller host>:<controller port> in your browser
