⚡️ Speed up method IncidentsApi.list_incidents_with_pagination by 25%

[codeflash-ai]

📄 25% (0.25x) speedup for IncidentsApi.list_incidents_with_pagination in src/datadog_api_client/v2/api/incidents_api.py

⏱️ Runtime : 103 microseconds → 82.3 microseconds (best of 42 runs)

📝 Explanation and details

The optimized code achieves a 25% speedup through a targeted optimization in the list_incidents_with_pagination method that eliminates an expensive function call in the common case.

Key Optimization:

The main performance gain comes from avoiding the get_attribute_from_path() call when page_size is explicitly provided. In the original code, this function was always called to retrieve the page size with a default of 10:

# Original - always calls get_attribute_from_path
local_page_size = get_attribute_from_path(kwargs, "page_size", 10)

The optimized version uses conditional logic to set local_page_size directly when page_size is provided:

# Optimized - avoids function call when page_size is set
if page_size is not unset:
    kwargs["page_size"] = page_size
    local_page_size = page_size
else:
    local_page_size = 10

Why This Works:

From the line profiler results, get_attribute_from_path() was consuming 42.2% of the total runtime (431.8μs out of 1.02ms) in the original code. This function performs string splitting, iteration, and exception handling even for simple cases. By bypassing it when the value is already known, the optimized version reduces this overhead significantly.

Performance Impact:

The optimization is most effective when page_size is explicitly provided (which is common in pagination scenarios), as it completely eliminates the expensive path traversal. Even when page_size is not provided, the simple assignment local_page_size = 10 is much faster than the generic path-based lookup.

Minor Improvements:

Additional small optimizations include reformatted imports and slight improvements to the get_attribute_from_path and set_attribute_from_path functions, but the pagination method optimization is the primary driver of the performance gain.
