Specifies the encryption key for a single Parquet column. More...

#include <key_metadata.hpp>

Public Attributes
std::string	column_name
	Parquet column path (e.g. "a.b.c").
std::vector< uint8_t >	key
	32-byte AES-256 key (INTERNAL mode).
std::string	key_id
	KMS key identifier (EXTERNAL mode).

Detailed Description

Specifies the encryption key for a single Parquet column.

For INTERNAL mode, key holds the raw 32-byte AES-256 key. For EXTERNAL mode, key_id holds the KMS identifier used to retrieve the key at runtime.
