⚡️ Speed up method OneNoteDataSource.groups_onenote_sections_get_parent_notebook by 17%

[codeflash-ai]

📄 17% (0.17x) speedup for OneNoteDataSource.groups_onenote_sections_get_parent_notebook in backend/python/app/sources/external/microsoft/one_note/one_note.py

⏱️ Runtime : 725 microseconds → 620 microseconds (best of 5 runs)

📝 Explanation and details

The optimization achieves a 16% runtime improvement by eliminating unnecessary object construction in the most common execution path.

Key optimization: The code now uses lazy initialization for query parameter objects. Instead of always creating a SectionsRequestBuilderGetQueryParameters() object (which takes ~369µs based on profiling), it only constructs this object when query parameters are actually provided.

Specific changes:

1. Conditional object creation: Added a check if select or expand or filter or orderby or search or (top is not None) or (skip is not None) before constructing the query parameters object
2. Lazy assignment: Only assigns config.query_parameters = query_params when query_params is not None

Why this works: The profiling shows that creating SectionsRequestBuilderGetQueryParameters() consumes significant time (10.4% of total execution). In most API calls where no query parameters are used, this object construction is pure overhead. By skipping it entirely when unnecessary, the optimization eliminates this bottleneck.

Performance impact: The test results show this optimization is particularly effective for:

• Basic API calls without query parameters (most common case)
• High-throughput scenarios with 100+ concurrent calls
• Error handling paths where query parameters are irrelevant

The optimization maintains identical functionality and API behavior while reducing CPU cycles in the dominant execution path, making it especially valuable for OneNote API integrations that primarily fetch basic notebook data without complex filtering or expansion.
