Support Reading Parquet Modular Encryption (PME) Files #9
Description
Description
Add support for reading Parquet files encrypted using Parquet Modular Encryption (PME) in DataFusion–DuckLake. This change enables decryption of footer- and column-level encrypted Parquet files by configuring Parquet execution with appropriate decryption properties. Encryption keys can be sourced from catalog metadata or external key providers, enabling secure access to encrypted datasets while preserving existing query behavior.
Current behavior: encryption_key field exists but unused
Desired behavior: Decrypt files using keys from catalog metadata or external key store
