Query Plan Prediction Accuracy

[ringo380]

Goal

Integrate with actual database execution plans and train models on production query performance data.

Proposed Improvements

• Add EXPLAIN plan parsing for MySQL, PostgreSQL, Oracle
• Collect execution statistics from production databases
• Train cost estimation models on actual query plans
• Implement cardinality estimation integration

Success Metrics

• Execution time prediction within 20% error margin
• Cost estimation accuracy >85%
• Plan structure prediction accuracy >80%
