Large CSV Ingestion Fixtures
Real 50MB to 250MB CSV fixtures for chunked imports, staging pipelines, row-count stress, and spreadsheet or ETL throughput validation.
Why This Workflow Matters
- Uses real CSV files instead of padded blobs, so parser behavior and delimiter handling remain meaningful at size.
- Pair 100MB and 250MB files with wide-table and embedded-JSON controls to separate throughput issues from schema-shape issues.
- Anchored to existing CSV and spreadsheet packs so large-file tests can reuse the same import workflow assets.
