Does anyone know if there are any workarounds like driver properties and timeouts that could be set to at least be able to get away with waiting a minute instead of force killing dbeaver? Amazon Redshift has an architecture that allows massively parallel processing using multiple nodes, reducing the load times. Is the current behavior that all queries of all cards on a dashboard execute together as a batch, so that if one of them stalls, the whole dashboard fails? @agilliland has pretty strong feelings here =), BTW, now that I look at this, that DATASET_TIMEOUT constant doesn't actually cause the query to be cancelled on the backend, it just rejects the client-side promise after 60 seconds ¯\_(ツ)_/¯.
