⚡ Bolt: Vectorize heat index calculation#18
Conversation
💡 What: Replaced row-wise `df.apply` with vectorized numpy operations in `nasa_data.py`. 🎯 Why: `df.apply` is slow for mathematical operations on DataFrames. 📊 Impact: Reduced execution time by ~85% (15.02 ms -> 2.22 ms) for 1 year of daily data (~6.7x speedup). 🔬 Measurement: Verified with a benchmark script using mocked NASA data. Results match the original implementation. Co-authored-by: cmonteverde <83616016+cmonteverde@users.noreply.github.com>

Replaced the
df.applymethod for calculating heat index with vectorized numpy operations. This significantly improves performance for large datasets. Also added a.gitignorefile to improve repository hygiene.PR created automatically by Jules for task 10767212174641754403 started by @cmonteverde
