Decision Factors

  • Ingestion support across BI/warehouse tooling.
  • Need for nested data versus flat tabular structures.
  • Delimiter collision frequency in raw data values.
  • Batch-oriented versus streaming processing model.

Common Mistakes to Avoid

  • Using CSV for deeply nested entities without flattening strategy.
  • Ignoring delimiter/quote normalization in source exports.
  • Skipping schema validation before ingestion jobs.
