I've noticed that when I query my Postgres database, DataGrip allows me to examine the explain plain (operations tree, Flame chart, visual graph) with operation, row, and cost information.
When I run (any) query on Snowflake, DataGrip returns an explain plan with the basic operations but no information on cost. I'm thinking that it is not returning information ex post query execution.
Is this expected behavior? This post makes me think that Snowflake doesn't support this outside of their GUI.
Yes, in Snowflake 'cost' is partition bytes in optimizer and we don't show them. But if you think it would be useful - feel free to fill up feature request on our tracker.
