Advanced LangGraph: Optimization, Debugging, and Monitoring Complex Graphs Training Course

Advanced LangGraph Architecture

• Graph topology patterns, including nodes, edges, routers, and subgraphs.
• State modeling techniques such as channels, message passing, and persistence.
• Differences between DAG and cyclic flows, along with hierarchical composition.

Performance and Optimization

• Parallelism and concurrency patterns in Python.
• Strategies for caching, batching, tool calling, and streaming.
• Implementing cost controls and token budgeting strategies.

Reliability Engineering

• Managing retries, timeouts, backoff mechanisms, and circuit breaking.
• Ensuring idempotency and deduplication of process steps.
• Implementing checkpointing and recovery using local or cloud storage stores.

Debugging Complex Graphs

• Performing step-through execution and dry runs.
• Inspecting system state and tracing events.
• Reproducing production issues using seeds and fixtures.

Observability and Monitoring

• Implementing structured logging and distributed tracing.
• Tracking operational metrics such as latency, reliability, and token usage.
• Setting up dashboards, alerts, and SLO tracking.

Deployment and Operations

• Packaging graphs as services and containers.
• Managing configurations and handling secrets securely.
• Establishing CI/CD pipelines, rollouts, and canary releases.

Quality, Testing, and Safety

• Developing unit, scenario, and automated evaluation harnesses.
• Implementing guardrails, content filtering, and PII handling protocols.
• Conducting red teaming and chaos experiments to ensure robustness.
