⚡️ Speed up method OneNoteDataSource.me_onenote_notebooks_section_groups_get_parent_section_group by 18%

[codeflash-ai]

📄 18% (0.18x) speedup for OneNoteDataSource.me_onenote_notebooks_section_groups_get_parent_section_group in backend/python/app/sources/external/microsoft/one_note/one_note.py

⏱️ Runtime : 1.33 milliseconds → 1.13 milliseconds (best of 19 runs)

📝 Explanation and details

The optimized code achieves a 17% runtime speedup by implementing conditional object allocation - a key optimization that avoids creating expensive Microsoft Graph SDK objects when they're not needed.

What was optimized:

• Added a has_query check that evaluates whether any query parameters are actually provided before creating the NotebooksRequestBuilderGetQueryParameters object
• Only instantiate query parameter objects when at least one parameter (select, expand, filter, orderby, search, top, skip) is non-empty/non-None
• Conditionally set config.query_parameters only when the query_params object exists

Why this leads to speedup:
The line profiler reveals the core performance bottleneck: creating NotebooksRequestBuilderGetQueryParameters() takes 943,347 nanoseconds in the original code (20.2% of total time). In the optimized version, this object is only created 5 times out of 412 calls, reducing this overhead to just 26,685 nanoseconds (0.7% of total time).

Most API calls in typical OneNote usage don't require query parameters - they're simple direct resource fetches. The optimization recognizes this pattern and eliminates unnecessary object instantiation for the common case while preserving full functionality when parameters are needed.

Performance impact by test type:

• Basic operations (no query params): Maximum benefit from avoiding object allocation entirely
• Complex queries (with select/expand/search): Minimal overhead from the additional has_query check
• Concurrent/high-volume scenarios: Consistent 17% improvement scales linearly across all test loads

The optimization is particularly effective for OneNote integrations that primarily fetch basic section group information without complex filtering or expansion, which represents the majority of real-world API usage patterns.
