With Parquet Modular Encryption 1. With each key rotation , Is it possible to avoid encryption and decryption of existing data?
2. If master key rotation does not require modification of the data file then how would the KMS work. 3. Do we have any constraints for key structure while updating a key. It would be better if you could provide a git link having the interface to implement KMS. I am already following this git page https://github.com/apache/parquet-format/blob/master/Encryption.md but still have a few doubts.
