📄 _get_google_cloud_logs_url() in sentry_sdk/integrations/gcp.py

📈 Performance improved by 6% (0.06x faster)

⏱️ Runtime went down from 268 microseconds to 252 microseconds

Explanation and details

To optimize the given function for runtime and memory utilization, you can make a few changes such as utilizing f-strings for faster string formatting and minimize calls to environ.get by storing the results in local variables. Here is the optimized version of the function.

Key Optimizations.

  1. Use of f-strings: These are faster than str.format() for string formatting in Python.
  2. Reduced environment variable accesses: Access environ.get only once for each variable to reduce dictionary lookups.

These changes can lead to a noticeable improvement in both performance and memory efficiency, especially in cases where the function is called repeatedly.

Correctness verification

The new optimized code was tested for correctness. The results are listed below.
