Broker Query API

REST API on the Broker

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

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.

When TLS/SSL is not enabled:

$ 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

When TLS/SSL is enabled:

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

If the SQL statement contains ", in the JSON body, it needs to be replaced by '"'"', for example:

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

Query Console

Use Query Console to run ad hoc queries. Access the Query Console by entering the <controller host>:<controller port> in your browser.

pinot-admin

You can also query using the pinot-admin scripts. Make sure you follow instructions in Getting Pinot to get Pinot locally, and then

cd incubator-pinot/pinot-tools/target/pinot-tools-pkg 
bin/pinot-admin.sh PostQuery \
  -queryType sql \
  -brokerPort 8000 \
  -query "select count(*) from baseballStats"
