gc.collect() is used to actively trigger garbage collection after processing each asset, promptly releasing objects that are no longer referenced, and handling circular references that Python reference counting cannot reclaim.

Partially VerifiedPython's `gc.collect()` can only reclaim objects in reference cycles and return the memory to the allocator; the operating system does not necessarily reclaim it immediately; heavy steps should be placed in a separate subprocess, so that the memory can be fully reclaimed by the operating system when the process exits.78% similarUnverifiedPython's gc.collect() interface can be called manually to promptly free objects no longer in use and avoid memory accumulation.76% similarUnverifiedThe Python runtime relies on CPython's reference-counting garbage collection, and occasional GC pauses under high-concurrency requests cause long-tail latency degradation.75% similarUnverifiedrows() 使用 Python 生成器（yield）而非返回列表，使内存占用与数据集大小解耦58% similarUnverifiedGenerators and iterators in Python are one-time data structures; iterating again after exhaustion yields no elements.56% similar
