- Incremental loads for large datasets
Prefect Solution:
Results:
- 70% reduction in pipeline failure rate
- 5x faster execution with parallel extraction
- Automatic recovery from API failures
- Full observability of each source
Use Case 2: Incremental Data Lake Sync
Scenario: Sync 10TB of event data from operational PostgreSQL to S3 data lake incrementally.
Challenges:
- Large dataset size
- Database load concerns
- Need for checkpointing
- Idempotency required
Prefect Solution:
Results:
- Zero data loss with checkpointing
- Database load distributed over time
- Resumable from any point
- Idempotent re-runs
