Specific answers for teams replacing Dataedo with ParquetColumnShield.
Every Parquet RowGroup stores ColumnChunk statistics containing the exact min_value and max_value for each column to speed up predicate pushdown. For string columns like email, SSN, or account_number, real customer PII is embedded directly in the file footer.
When diagnosing schema evolution, partition skew, or predicate pushdown bugs in Spark, Trino, or Iceberg, removing columns alters the schema ordinal positions and breaks downstream SQL readers. ParquetColumnShield masks values in place while preserving every column name and type.
Data engineers often commit small parquet-tools JSON dumps or PyArrow schema snapshots as unit test fixtures, which get blocked when custom key_value_metadata contains S3 tokens or row samples contain live tokens. ParquetColumnShield scrubs both.
Yes. It traverses nested JSON representations of Parquet STRUCT, LIST, and MAP columns to mask inner PII fields while keeping repetition and definition structure intact.
Never. All parsing, footer statistic scrubbing, and Canvas column-density visualization execute 100% locally inside your browser memory with zero network egress.
