In addition to what Rok has said, I just want to add that integration with PyArrow is a bit more complicated than C++ Arrow and other implementations, as PyArrow doesn't expose the low-level encryption API where you can set AES keys directly. PyArrow only provides the "key management tools" API (see [this design doc](https://docs.google.com/document/d/1bEu903840yb95k9q2X-BlsYKuXoygE4VnMDl9xz_zhk/edit?usp=sharing)), which requires users to implement a client for a Key Management Service. Data encryption keys are randomly generated and encrypted with the KMS and these encrypted keys are stored in the Parquet metadata. This isn't a part of the official Parquet spec, but is implemented by parquet-java / Spark too. -- This is an automated message from the Apache Git Service.
