@cloud-fan Thanks for the review. The following changes are made: - The logic are merged into the existing RewriteDistinctAggregates rule, only fires when we actually need to do the rewrite: a lone COUNT DISTINCT will still go with the cheap non-Expand path. - Optimized the test suites to check more concrete details of the optimized plan. -- This is an automated message from the Apache Git Service.
