The core principle governing file processing in computational systems is the utilization of lazy iteration, where data streams are consumed sequentially via buffered reading rather than being fully loaded into memory at once. This mechanism, characterized by file objects acting as iterators, ensures memory efficiency by retrieving only a small buffer of upcoming elements during traversal. The theory posits that sequential access patterns are strictly required for large-scale data handling to prevent memory exhaustion, distinguishing this approach from eager loading methods that ingest entire datasets simultaneously.
