Hi, what is the best way to load database credentials if using within a node? In my use case I want to call snowflake directly in a node as I can’t define the query until data processing has taken place. I.e., I don’t know what the parameters of the query will be until the node runs, and I can’t see how I could make a PandasSqlQuery dataset use dynamic parameters. Given this, I think I need to somehow create a sqlalchemy engine using credentials within my node. However, I see that passing the context around is not recommended.
