QueryLab
Analyzes PostgreSQL execution plans to identify bottlenecks such as join amplification, disk spills, and planner estimation errors.
Key Features
Execution Plan Analysis
Parses PostgreSQL EXPLAIN ANALYZE output into a traversable execution tree for rule-based analysis.
Derived Performance Metrics
Calculates self-time, row amplification, and cardinality mismatch metrics during recursive tree traversal.
Heuristic Rule Engine
Evaluates execution nodes against performance rules to surface expensive joins, sequential scans, and disk spills.
