⚡️ Speed up method LangSmithTracer.add_trace by 18% in src/backend/base/langflow/services/tracing/langsmith.py

[codeflash-ai]

📄 LangSmithTracer.add_trace in src/backend/base/langflow/services/tracing/langsmith.py

✨ Performance Summary:

• Speed Increase: 📈 18% (0.18x faster)
• Runtime Reduction: ⏱️ From 3.20 microseconds down to 2.71 microseconds (best of 16 runs)

📝 Explanation and details

Here's the optimized version of the provided Python program.

Changes Made.

1. Removed redundant import statement: Moved RunTree import inside the outer try block to the module scope as it is imported unconditionally if setup_langsmith is ready.
2. Optimized _convert_to_langchain_types method: Used dictionary comprehension instead of a loop for conversion.
3. Eliminated redundant step in add_trace method: Direct dictionary comprehension in processed_inputs.
