prefetch() in Odoo

In Odoo, the prefetch() function optimizes data retrieval by reducing the number of database queries during record operations. It loads related records into memory, minimizing repetitive queries when accessing fields from multiple records. Grouping similar queries improves performance in operations like loops, views, and reports. The function is automatically triggered in many scenarios but can be manually invoked for custom models or computations, handling large datasets while maintaining data consistency.
