File Path Metadata in Lakehouse Pipelines
Execution context is not stable lineage metadata.
Details are generalized and sanitized to preserve confidentiality while keeping the engineering lesson accurate.
Problem
A common issue is file-path lineage inferred from runtime context becoming null or incomplete in production runs.
Approach
Move metadata capture to ingestion-source fields (for example, structured file metadata from the input stream) and log resolved path values explicitly.
Reusable pattern
- Use ingestion-source metadata for lineage.
- Avoid deriving file identity from runtime context.
- Log resolved source path and metadata fields.
