📄 EntrypointOutput.is_in_logs() in airbyte-cdk/python/airbyte_cdk/test/entrypoint_wrapper.py

📈 Performance improved by 92% (0.92x faster)

⏱️ Runtime went down from 11.7 milliseconds to 6.07 milliseconds

Explanation and details

To optimize the given Python program for faster execution, we'll focus on improving the list comprehension within the __init__ method and optimizing the is_in_logs method. We will use more efficient coding practices and eliminate unnecessary operations where possible.

Here's the optimized version of the program.

Changes and Improvements.

1. List Comprehension to For Loop: Converted the list comprehension in __init__ method to a for loop for clarity and debugging ease.
2. Cache the Compiled Regex: In is_in_logs, precompiled the regex pattern outside the loop. This avoids recompiling the pattern on every iteration which is more efficient.
3. Direct Filtering in Logs: Simplified _get_message_by_types logic by using direct filtering inline in the logs property.

Correctness verification

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