From 521c24c5c36377307372008d4e6c81dc7addb60a Mon Sep 17 00:00:00 2001 From: Kai Huang Date: Mon, 10 Nov 2025 14:44:12 -0800 Subject: [PATCH 01/22] Implement reverse performance optimization This commit optimizes the `reverse` command in the Calcite planner by intelligently reversing existing sort collations instead of always using the ROW_NUMBER() approach. Key changes: - Added PlanUtils.reverseCollation() method to flip sort directions and null directions - Updated CalciteRelNodeVisitor.visitReverse() to: - Check for existing sort collations - Reverse them if present (more efficient) - Fall back to ROW_NUMBER() when no sort exists - Added comprehensive integration test expected outputs for: - Single field reverse pushdown - Multiple field reverse pushdown - Reverse fallback cases - Double reverse no-op optimizations This optimization significantly improves performance when reversing already-sorted data by leveraging database-native sort reversal.
