@jorgecarleitao > Doesn't this mean that the plan can fail arbitrarily when a user performs an impossible cast? This can happen like 10hs after the execution starts, when the query finally reaches that point. Yes I think that is accurate. > Isn't it possible to expand can_coerce_from to cover the cases that DataFusion is missing but that arrow cast kernel supports? Yes I can do that -- my rationale for this proposal was to avoiding having to keep two lists of valid typecasts in sync. However, the value of faster errors is a valid point. I will make a new PR to do as you suggest and expand the coverage in `can_coerce_from` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
