Trino

Start running Trino Image with pre-built Trino Pinot connector.
Kubernetes
1. Install Pinot
Run below command to install Pinot using HelmCharts.
helm repo add pinot https://raw.githubusercontent.com/apache/pinot/master/kubernetes/helm
kubectl create ns pinot-quickstart
helm install pinot pinot/pinot -n pinot-quickstart --set cluster.name=pinot
​
You can create an example table by running the command below, if you are under pinot binary directory
Before PR https://github.com/trinodb/trino/pull/7630 got merged, Change the Pinot table name to all lower cases for table conf/schema and ingestion job spec
bin/pinot-admin.sh BootstrapTable -dir examples/batch/airlineStats
​
2. Install Trino
Run below command to add Trino Helm repo and fetch default helm config file:
helm repo add trino https://trinodb.github.io/charts/
helm inspect values trino/trino > /tmp/trino.yaml
​
Edit /tmp/trino.yaml file to add your pinot catalog:
Here, since pinot is deployed at namespace pinot-quickstart, so the controller url is pinot-controller.pinot-quickstart:9000
additionalCatalogs:
  pinot: |
    connector.name=pinot
    pinot.controller-urls=pinot-controller.pinot-quickstart:9000
​
Install Trino HelmCharts with config file:
helm create ns trino-quickstart
helm install my-trino trino/trino --version 0.2.0 --values /tmp/trino.yaml -n trino-quickstart 
3. Connecting to Trino
Download Trino Client.
curl -L https://repo1.maven.org/maven2/io/trino/trino-cli/363/trino-cli-363-executable.jar -o /tmp/trino && chmod +x /tmp/trino
Port forward Trino service to your local if it's not already exposed.
export POD_NAME=$(kubectl get pods --namespace trino-quickstart -l "app=trino,release=my-trino,component=coordinator" -o jsonpath="{.items[0].metadata.name}")
echo "Visit http://127.0.0.1:8080 to use your application"
kubectl port-forward $POD_NAME 8080:8080 --namespace trino-quickstart
Use Trino console client to connect to Trino service
/tmp/trino --server localhost:8080 --catalog pinot --schema default
Then write your own queries:
trino:default> show tables;
     Table
