Two of these formats (Parquet and ORC) have built-in encryption capabilities, that allow to protect sensitive information in the data files. However, besides the data files, Iceberg tables also have metadata files, that keep sensitive information too (e.g., min/max values in manifest files, or bloom filter bitsets in puffin files). Metadata file formats (AVRO, JSON, Puffin) don't have encryption support. + +Moreover, with the exception of Parquet, no Iceberg data or metadata file format supports integrity verification, required for end-to-end tamper proofing of Iceberg tables. + +This document specifies details of a simple file format extension that adds encryption and tamper-proofing to any existing file format. Review Comment: I think this should be more clear that the proposal is to encrypt an entire stream, which will prevent skipping in the underlying file. -- This is an automated message from the Apache Git Service.
