JSON Transformation Functions

In this recipe we'll learn how to use JSON transformation functions to extract values from nested JSON documents.

Pinot Version 1.0.0
Schema config/schema.json
Table Config config/table.json
Ingestion Job config/job-spec.yml

This is the code for the following recipe: https://dev.startree.ai/docs/pinot/recipes/json-transformation-functions

Clone this repository and navigate to this recipe:

git clone [email protected]:startreedata/pinot-recipes.git
cd pinot-recipes/recipes/json-transformation-functions

Spin up a Pinot cluster using Docker Compose:

docker compose up

Open another tab to add the people table:

docker run \
   --network json \
   -v $PWD/config:/config \
   apachepinot/pinot:1.0.0 AddTable \
     -schemaFile /config/schema.json \
     -tableConfigFile /config/table.json \
     -controllerHost "pinot-controller-json" \
    -exec

Import data/ingest.json into Pinot:

docker run \
   --network json \
   -v $PWD/config:/config \
   -v $PWD/data:/data \
   apachepinot/pinot:1.0.0 LaunchDataIngestionJob \
    -jobSpecFile /config/job-spec.yml

Navigate to http://localhost:9000/#/query and run the following query:

select * 
from people 
limit 10
