- Updated `update_current_trace` function to accept dynamic keyword arguments, simplifying the process of updating trace metadata. - Enhanced `Trace` class to merge new metadata with existing fields, allowing for more efficient metadata management. This refactor aims to streamline trace updates and improve code maintainability.

Summary
This PR introduces new functions,
update_current_trace()andupdate_current_span(), allowing users to dynamically set and update metadata (e.g.,user_id, custom attributes, tags) at the trace and span level during execution.Changes
update_current_trace()to set/merge trace-level metadata.update_current_span()to set/merge current step/span metadata.Traceclass to store and update new root-level metadata fields.examples/tracing/trace_metadata_updates.py) demonstrating usage.Context
This functionality addresses the need for greater flexibility in tracing complex agent and LLM workflows. Users can now enrich traces with critical context (like
user_idor session variables) without needing to pass them as explicit function arguments, which is often impractical in non-standard or deeply nested application patterns. This improves observability and enables more advanced tracing use cases.Testing
