📄 Description

Depends on https://github.com/langchain-ai/langchain-google/pull/1538#

Summary

This PR updates the BigQuery callback handler documentation to include comprehensive LangGraph support features that were added in langchain-ai/langchain-google#1538.

What's new in the documentation:

  • Updated description - Mentions LangGraph support alongside LangChain
  • Key features section - Highlights LangGraph detection, latency tracking, event filtering, graph context manager, and real-time dashboard
  • LangGraph integration section - Explains automatic node detection and new event types
  • Event types table - Documents NODE_STARTING, NODE_COMPLETED, GRAPH_START, GRAPH_END events
  • Graph context manager - Shows how to use graph_context() for execution boundaries
  • Latency tracking - Includes SQL query example for analytics
  • Event filtering - Demonstrates allowlist/denylist configuration
  • Updated example code - Uses LangGraph's create_react_agent with proper configuration
  • Examples and resources section - Links to example agent, Jupyter notebook, and FastAPI webapp

LangGraph Event Types Table

Event Type Description
NODE_STARTING Emitted when a LangGraph node begins execution
NODE_COMPLETED Emitted when a LangGraph node finishes successfully
NODE_ERROR Emitted when a LangGraph node fails
GRAPH_START Emitted at the start of graph execution (via context manager)
GRAPH_END Emitted at the end of graph execution (via context manager)
GRAPH_ERROR Emitted when graph execution fails (via context manager)

Test plan

  • Verified example code runs successfully with LangGraph agent
  • Confirmed events are logged to BigQuery with correct event types
  • Tested graph_context() emits GRAPH_START/GRAPH_END events
  • Validated SQL query examples return expected results
