@xudong963 I was thinking we can simply derive the proportion of unique values on the left side, given that we collect the left side in memory. If the left side has a high number of distinct values for a given column, it may be more likely that the right side follows this as well. In which case pushing down the literal values could be better so lower nodes can take advantage of row/group pruning. -- This is an automated message from the Apache Git Service.
