I have installed Apache Superset on AWS using the quick start guide (https://aws-quickstart.github.io/quickstart-apache-superset/) and it is all working fine. The only issue I have is that my dataset is very large, so some queries take more than 60 seconds to run and superset times out. I know that I should increase the time out in the superset_config.py file to include SUPERSET_TIMEOUT=xxx and also SQLLAB_TIMEOUT=xxx but I can't seem to find this file. Any ideas on where this could be and how to edit the file?
