SQL Lab Trino, no cost estimate button

[tarekabouzeid]

Hi,

I am using Superset 2.0.1 and i have added a Trino connection and enabled "Enable query cost estimation". But when I open data lab I don't see the cost estimate button. It is written inside an info box that query cost estimation " For Presto and Postgres, shows a button to compute cost before running a query." Does that mean this feature is not available for Trino at all ?

Thanks

Hi @tarekabouzeid, to enable cost estimation for Trino, first you need to change superset_config.py file:

FEATURE_FLAGS = {
    "ESTIMATE_QUERY_COST": True
}

Next, specify the version of Trino that you are using in the Advanced > Other > Version in the Database Connections setup on Superset.
