JiraDataSource.app_issue_field_value_update_resource_update_issue_fields_putinbackend/python/app/sources/external/jira/jira.py⏱️ Runtime :
1.60 milliseconds→1.32 milliseconds(best of51runs)📝 Explanation and details
The optimized code achieves a 21% runtime improvement (1.60ms → 1.32ms) through several targeted micro-optimizations that reduce overhead in object allocation and unnecessary operations:
Key Optimizations Applied:
Eliminated unnecessary URL formatting: The original code called
_safe_format_url(rel_path, _path)where_pathwas always empty. The optimized version directly concatenatesself.base_url + rel_path, bypassing the format operation entirely. This saves ~18% of the original function's time (line profiler shows this dropped from 18% to 1.9% of total time).Reduced dictionary allocations: Instead of creating three separate empty dictionaries (
_path,_query,_body), the optimized version eliminates_pathand_queryentirely since they're always empty, and uses a conditional expression for_bodycreation that only allocates the dictionary whenupdateValueListis provided.Optimized header handling: Replaced
dict(headers or {})+setdefault()with a more direct conditional copy (headers.copy() if headers else {}) followed by an explicitifcheck for Content-Type, avoiding the overhead of thesetdefaultmethod call.Improved
_as_str_dictefficiency: Added a check to avoid callingstr()on keys that are already strings (k if isinstance(k, str) else str(k)), reducing unnecessary type conversions.Streamlined HTTPRequest creation: Passes empty dictionaries directly instead of calling
_as_str_dicton empty collections, eliminating unnecessary function calls.Performance Impact:
The line profiler shows the main function's total time reduced from 6.02ms to 4.00ms, with the most significant gains coming from eliminating the
_safe_format_urloverhead and reducing_as_str_dictcalls. The_as_str_dictfunction time also improved from 1.33ms to 0.98ms.Test Case Effectiveness:
These optimizations are particularly effective for the high-throughput scenarios tested, including concurrent execution (5-50 parallel calls) and large payloads (100+ field updates). The improvements benefit all usage patterns since they target fundamental operations performed in every function call, making this optimization valuable for any workload that frequently calls this Jira API endpoint.
