⚡️ Speed up method ApiKeyRead.mask_api_key by 7% in src/backend/base/langflow/services/database/models/api_key/model.py

[codeflash-ai]

📄 ApiKeyRead.mask_api_key in src/backend/base/langflow/services/database/models/api_key/model.py

✨ Performance Summary:

• Speed Increase: 📈 7% (0.07x faster)
• Runtime Reduction: ⏱️ From 171 microseconds down to 160 microseconds (best of 18 runs)

📝 Explanation and details

Certainly! Here is the optimized version of the given Python program.

Explanation of Changes.

1. Avoid String Interpolation in Favor of Concatenation: String concatenation is generally faster than interpolation using f-strings in Python. Therefore, replacing the f-string with direct concatenation can improve performance slightly.
