⚡️ Speed up method OneNoteDataSource.me_onenote_notebooks_section_groups_sections_pages_get_parent_section by 15%

[codeflash-ai]

📄 15% (0.15x) speedup for OneNoteDataSource.me_onenote_notebooks_section_groups_sections_pages_get_parent_section in backend/python/app/sources/external/microsoft/one_note/one_note.py

⏱️ Runtime : 823 microseconds → 716 microseconds (best of 5 runs)

📝 Explanation and details

The optimized code achieves a 15% performance improvement through two key optimizations:

1. Conditional Object Creation (Primary Optimization)

The main optimization eliminates unnecessary object creation by adding a conditional check before instantiating the NotebooksRequestBuilderGetQueryParameters object:

# Only create query parameters if needed to avoid unnecessary object creation
if (select or expand or filter or orderby or search or
    top is not None or skip is not None):
    query_params = NotebooksRequestBuilder.NotebooksRequestBuilderGetQueryParameters()
    # ... set parameters
else:
    query_params = None

This prevents creating the query parameters object when no query parameters are provided, which is the common case. The line profiler shows this object creation took 426.7ms in the original code but is now skipped entirely when not needed.

2. Streamlined Error Response Handling

The _handle_onenote_response method was optimized by using early returns instead of setting intermediate variables:

• Before: Set success=True and error_msg=None variables, then conditionally modify them
• After: Return immediately when error conditions are detected, eliminating unnecessary variable assignments

This reduces the total time in _handle_onenote_response from 754.6μs to 663.8μs (12% improvement).

Performance Impact

The optimization is particularly effective for OneNote API calls without query parameters (the most common scenario), where object creation overhead is completely eliminated. The 15% runtime improvement (823μs → 716μs) comes primarily from avoiding expensive object instantiation when it's not needed.

Since OneNote operations are typically called frequently in document management workflows, this optimization reduces cumulative overhead across multiple API calls, making the system more responsive when processing OneNote data.
