Hi, I would like to work on this issue! I have analyzed the root cause ,the Precision::Exact branch in max_distinct_count uses a plain subtraction (count - null_count) which can overflow when null_count > count after a fetch/limit pushdown via HashJoinExec. The fix is to apply the same checked_sub pattern already used in the Inexact branch. Could you please assign this issue to me? Thanks! -- This is an automated message from the Apache Git Service.
