Implementation Details

Subgraph Patterns

1. Compiled Subgraphs: Pre-compiled reusable components
2. State Mapping: Input/output state transformation
3. Nested Subgraphs: Multi-level graph composition
4. Parallel Subgraphs: Concurrent subgraph execution

Configuration Options

• State schema alignment
• Input/output key mapping
• Error propagation settings
• Subgraph checkpoint inheritance
• Timeout configurations

Best Practices

• Clear subgraph interfaces
• Minimal state coupling
• Proper error boundaries
• Reusable component design
• Documentation for subgraph contracts
