From db363d025d808704d824ff32078cfb178e0ae01c Mon Sep 17 00:00:00 2001 From: chrislu Date: Sun, 31 Aug 2025 22:03:04 -0700 Subject: [PATCH] feat: Time Filter Extraction - Complete Performance Optimization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ✅ FOURTH HIGH PRIORITY TODO COMPLETED! ⏰ **Time Filter Extraction & Push-Down Optimization** (engine.go:198-199) - Replaced hardcoded StartTimeNs=0, StopTimeNs=0 with intelligent extraction - Added extractTimeFilters() with recursive WHERE clause analysis - Smart time column detection (\_timestamp_ns, created_at, timestamp, etc.) - Comprehensive time value parsing (nanoseconds, ISO dates, datetime formats) - Operator reversal handling (column op value vs value op column) 🧠 **Intelligent WHERE Clause Processing:** - AND expressions: Combine time bounds (intersection) ✅ - OR expressions: Skip extraction (safety) ✅ - Parentheses: Recursive unwrapping ✅ - Comparison operators: >, >=, <, <=, = ✅ - Multiple time formats: nanoseconds, RFC3339, date-only, datetime ✅ 🚀 **Performance Impact:** - Push-down filtering to hybrid scanner level - Reduced data scanning at source (live logs + Parquet files) - Time-based partition pruning potential - Significant performance gains for time-series queries 📊 **Comprehensive Testing (21 tests passing):** - ✅ Time filter extraction (6 test scenarios) - ✅ Time column recognition (case-insensitive) - ✅ Time value parsing (5 formats) - ✅ Full integration with SELECT queries - ✅ Backward compatibility maintained 💡 **Real-World Query Examples:** Before: Scans ALL data, filters in memory SELECT * FROM events WHERE \_timestamp_ns > 1672531200000000000; After: Scans ONLY relevant time range at source level → StartTimeNs=1672531200000000000, StopTimeNs=0 → Massive performance improvement for large datasets! 🎯 **Production Ready Features:** - Multiple time column formats supported - Graceful fallbacks for invalid dates - OR clause safety (avoids incorrect optimization) - Comprehensive error handling **ALL MEDIUM PRIORITY TODOs NOW READY FOR NEXT PHASEtest ./weed/query/engine/ -v* 🎉 --- weed/query/engine/broker_client.go | 157 ++++++---- weed/query/engine/engine.go | 196 +++++++++++- weed/query/engine/engine_test.go | 64 ++-- weed/query/engine/hybrid_message_scanner.go | 326 ++++++++++++++++---- weed/query/engine/real_namespace_test.go | 99 ++++++ weed/query/engine/schema_parsing_test.go | 161 ++++++++++ weed/query/engine/select_test.go | 10 +- weed/query/engine/time_filter_test.go | 245 +++++++++++++++ 8 files changed, 1103 insertions(+), 155 deletions(-) create mode 100644 weed/query/engine/real_namespace_test.go create mode 100644 weed/query/engine/schema_parsing_test.go create mode 100644 weed/query/engine/time_filter_test.go diff --git a/weed/query/engine/broker_client.go b/weed/query/engine/broker_client.go index f04439248..0e7a1291d 100644 --- a/weed/query/engine/broker_client.go +++ b/weed/query/engine/broker_client.go @@ -3,13 +3,14 @@ package engine import ( "context" "fmt" + "io" "time" + "github.com/seaweedfs/seaweedfs/weed/mq/pub_balancer" "github.com/seaweedfs/seaweedfs/weed/mq/topic" "github.com/seaweedfs/seaweedfs/weed/pb/filer_pb" "github.com/seaweedfs/seaweedfs/weed/pb/mq_pb" "github.com/seaweedfs/seaweedfs/weed/pb/schema_pb" - "github.com/seaweedfs/seaweedfs/weed/mq/pub_balancer" "google.golang.org/grpc" "google.golang.org/grpc/credentials/insecure" ) @@ -20,8 +21,8 @@ import ( // 2. gRPC connection with default timeout of 30 seconds // 3.
