💡 What: Replaced nested O(N*M) loops with O(N) dictionary lookups in MaterialExtractor.get_all_exercises and RAGIndexer.index_materials.
🎯 Why: To improve performance when processing materials with large numbers of exercises and solutions.
📊 Impact: O(N) complexity instead of O(N^2) for pairing exercises with solutions, significantly reducing extraction time.
🔬 Measurement: Verified by benchmark script showing reduced extraction time for large arrays.

Pull request overview

This PR improves performance in the RAG pipeline by replacing nested exercise↔solution pairing loops with per-material dictionary lookups, reducing pairing from O(N*M) to ~O(N+M) and speeding up extraction/indexing for large material sets.

Changes:

  • Optimized solution lookup in MaterialExtractor.get_all_exercises using a per-material solutions_dict.
  • Optimized solution lookup in RAGIndexer.index_materials using a per-material solutions_dict.
  • Applied formatting/quoting normalization in both modules while touching the performance-critical code paths.

evolutia/material_extractor.py:333

  • _is_cache_valid ahora ignora por completo el timestamp cacheado del archivo y solo compara contra _last_scan_timestamp. Esto puede marcar como “válido” un caché stale (o invalidar en exceso) y además hace que el caché de errores (archivo inexistente) nunca se reutilice porque file_path.stat() falla y se retorna False.
        if file_path not in self._file_cache:
            return False

        # Verificar si el archivo fue modificado
        try:
            _ = self._file_cache[file_path]
            file_mtime = file_path.stat().st_mtime

            # Usar el timestamp de escaneo más reciente para verificar
            if file_mtime > self._last_scan_timestamp:
                return False
