Q: Is the Python integration safe for sensitive data?

Local Python runs in the same memory space as Stata. For encrypted data, ensure your Python environment is similarly secured. StataCorp advises against using external Python packages with unverified code. Stata 18

5. Data Management and Import/Export

  • Parquet Support: Stata 18 can read and write Apache Parquet files (import parquet, export parquet), a columnar storage format common in big data pipelines (Spark, Python, R). This allows Stata to handle datasets far larger than RAM.
