# Advanced Workflows

Complex end-to-end scenarios and real-world data engineering patterns.

## Examples

- late_arriving_reprocess/ - Self-healing pipelines for out-of-order data
- external_python_logic/ - Custom logic via notebooks
- payments_lifecycle/ - Multi-entity lifecycle and SCD2
- insurance_elt/ - Full end-to-end industry scenario
- shared_governance_scale/ - Shared transformations and validation at scale

## When to Use Each Pattern

- Self-heal aggregates: late_arriving_reprocess
- Custom complex logic: external_python_logic
- Stateful event tracking: payments_lifecycle
- Full industry template: insurance_elt
- Shared governance at scale: shared_governance_scale

## Prerequisites

- Complete 02_core_patterns/ to understand building blocks
- Familiarity with the Data as a Product vision

## Next Steps

- 07_production/ for monitoring and deployment
- docs/patterns/ for deeper theory
