Add Trino dataset to Apache Superset - kubernetes

Question

I have currently Trino deployed in my Kubernetes cluster using the official Trino(trinodb) Helm Chart. In the same way I deployed Apache superset.
Using port forwarding of trino to 8080 and superset to 8088, I am able to access the UI for both from localhost but also I am able to use the trino command line API to query trino using:
./trino --server http:localhost:8080
I don't have any authentication set
mysql is setup correctly as Trino catalog
when I try to add Trino as dataset for Superset using either of the following sqlalchemy URLs:
trino://trino#localhost:8080/mysql
trino://localhost:8080/mysql
When I test the connection from Superset UI, I get the following error:
ERROR: Could not load database driver: TrinoEngineSpec
Please advise how I could solve this issue.

Answer 1

You should install sqlalchemy-trino to make the trino driver available.
Add these lines to your values.yaml file:
additionalRequirements:
- sqlalchemy-trino
bootstrapScript: |
#!/bin/bash
pip install sqlalchemy-trino &&\
if [ ! -f ~/bootstrap ]; then echo "Running Superset with uid {{ .Values.runAsUser }}" > ~/bootstrap; fi
If you want more details about the problem, see this Github issue.
I added two options that do the same thing because in some versions the additionalRequirements doesn't work and you may need the bootstrapScript option to install the driver.
