⚡️ Speed up method JiraDataSource.delete_issue_type_property by 18%

[codeflash-ai]

📄 18% (0.18x) speedup for JiraDataSource.delete_issue_type_property in backend/python/app/sources/external/jira/jira.py

⏱️ Runtime : 2.42 milliseconds → 2.05 milliseconds (best of 40 runs)

📝 Explanation and details

The optimized code achieves a 17% runtime improvement through strategic reduction of dictionary operations and type checking overhead:

Key Optimizations:

1. Smart Header Processing: Instead of always calling dict(headers or {}), the code now checks if headers are None (common case) or already a Dict[str, str] and avoids unnecessary conversion. This eliminates redundant dict allocations for the majority of calls.

2. Optimized String Dictionary Conversion: The new _fast_as_str_dict() function checks if a dictionary is already Dict[str, str] before performing expensive string conversions. Since _path parameters are typically already strings, this avoids the costly _serialize_value() calls seen in the profiler.

3. Query Parameter Bypass: Since _query is always empty in this method, the optimization directly passes an empty dict {} instead of processing it through _fast_as_str_dict(), eliminating unnecessary function calls.

4. HTTP Client Path Optimization: The HTTPClient now avoids string formatting when path_params is empty and optimizes header merging by checking if request headers are empty before creating a new merged dictionary.

Performance Impact:
The line profiler shows significant reductions in time spent on dictionary operations - _as_str_dict() calls dropped from 2.94ms total time in the original to much faster _fast_as_str_dict() calls. The optimization is particularly effective for typical API calls with string parameters and minimal headers.

Test Case Performance:
The optimizations excel in high-throughput scenarios (100-200 concurrent calls) and basic use cases with simple string parameters, making this ideal for bulk API operations common in JIRA integrations.
