📄 21% (0.21x) speedup for OpikTracer.get_required_variable_names in src/backend/base/langflow/services/tracing/opik.py

⏱️ Runtime : 1.61 microseconds → 1.33 microsecond (best of 14 runs)

📝 Explanation and details

To optimize the code for faster execution, we can make a few changes related to avoiding unnecessary function calls, improving memory usage, and setting values more efficiently.

1. Move the call to OpikTracer.get_required_variable_names() out of the loop in __init__() to avoid redundant function calls.
2. Eliminate unnecessary intermediate variables where possible.

Here's the optimized version of the code.

Changes made.

1. Called get_required_variable_names() once and stored the result in required_variables to avoid redundant function calls.
2. Added a check for global_vars before the loop to avoid iterating if global_vars is None.

These changes should help in reducing the function call overhead and avoiding unnecessary computations, thus potentially improving the runtime.
