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
