⚡️ Speed up method RestClientInterface.PATCH by 15%

[codeflash-ai]

📄 15% (0.15x) speedup for RestClientInterface.PATCH in pinecone/openapi_support/rest_utils.py

⏱️ Runtime : 64.1 microseconds → 55.6 microseconds (best of 462 runs)

📝 Explanation and details

The optimization converts all keyword arguments in the self.request() call to positional arguments. Instead of passing headers=headers, query_params=query_params, body=body, post_params=post_params, _preload_content=_preload_content, _request_timeout=_request_timeout, the optimized version passes these as positional arguments in the correct order: query_params, headers, body, post_params, _preload_content, _request_timeout.

This optimization works because Python's keyword argument handling involves creating a dictionary to map argument names to values, then unpacking this during the function call. Positional arguments bypass this overhead entirely, as they can be directly assigned to parameters by position.

The line profiler results show the optimization primarily reduces time spent on the self.request() call itself (from 139,588ns to 129,087ns), while individual argument preparation becomes slightly more efficient across all parameters.

The test results demonstrate consistent 5-32% speedups across various scenarios, with the largest gains occurring in simpler cases (minimal arguments: 22.9% faster) and complex cases with large data structures (large combination test: 22.0% faster). The optimization is particularly effective for frequently called REST operations where function call overhead becomes significant.
